 **Vulnerability:** The backend CSV export for audit logs neutralized `=`, `+`, `-`, and `@` but failed to neutralize `|` (pipe) characters, allowing potential DDE (Dynamic Data Exchange) injection if exported logs were opened in spreadsheet software.
 **Learning:** Spreadsheet formula defenses must cover all command-style prefixes including `|` across all CSV export boundaries, both frontend and backend.
 **Prevention:** Update the sanitization regex in the backend export function to `/^[=+\-@|]/` so that all potentially executable spreadsheet payloads are prefixed with a single quote.
+## 2026-09-01 - Prevent SSRF via webhook URLs
+**Vulnerability:** The `/api/orgs/:id/webhooks` POST endpoint accepted any valid HTTP/HTTPS URL, including internal IP addresses and loopback domains (`127.0.0.1`, `localhost`, etc). This allowed Server-Side Request Forgery (SSRF).
+**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.
+**Prevention:** Always validate webhook URLs against a known blocklist of internal and loopback IP addresses (like `127.x.x.x`, `10.x.x.x`, `169.254.x.x`, `localhost`) to prevent SSRF vulnerabilities.

+# Product–technical gap baseline
+
+This baseline is derived from the current ScopeWeave source and is updated with executable evidence rather than aspirational status.
+
+## Bounded-context baseline
+
+ScopeWeave currently contains five product responsibilities. **Planning** is the core subdomain and owns projects, task structures, revisions, baselines, schedule data, and optimistic-concurrency invariants. **Workspace Access** is a supporting subdomain and owns organizations, membership, invitations, OIDC, personal access tokens, and authorization. **Integration Delivery** is a supporting subdomain and owns webhook registration, signed-event delivery, retry outcomes, and its outbound-network security policy. **Commercial Entitlement** is a supporting subdomain and owns plans, usage limits, and checkout. **Operational Telemetry** is a generic subdomain and owns request/delivery metrics and operational logs; it is not an authoritative audit or domain-event store.
+
+The Integration Delivery context must depend on a narrow outbound-network adapter rather than embedding DNS/TLS/HTTP policy in Hono route orchestration. Persisted webhook facts remain owned by ScopeWeave; socket selection, DNS resolution, TLS, redirect policy, and timeout behavior belong to the delivery adapter. External network behavior is an anti-corruption boundary: DNS answers or HTTP redirect targets never become trusted domain facts merely because a webhook record was previously accepted.
+
+## Current security gap: outbound webhook SSRF
+
+| Evidence | Status | Acceptance contract |
+| --- | --- | --- |
+| PR #649 original head `ce31e62667cb3a3b7d0deb79c5464952f27dd63c` added registration-time hostname prefix checks only. | FAIL | Registration accepts HTTPS only, rejects credentials/local/special-purpose literal addresses, and does not mistake ordinary DNS labels for IP literals. |
+| Exact-head production-boundary RED introduced on `e84c47c95ef86da416e361704c8b89675227fcf6`. | RED | A pre-existing persisted loopback webhook must receive zero network requests; the failed delivery must be recorded and stay within the bounded retry contract. |
+| Current reviewers identified DNS rebinding/resolution, IPv6, redirects, plaintext HTTP, public numeric-looking hostname false positives, and nondeterministic external-network smoke tests. | OPEN until GREEN | Every delivery attempt re-resolves through the operating-system resolver at the socket boundary, rejects any non-public answer, pins the connection to validated answers, disables redirect following, preserves TLS verification, and uses deterministic network seams in tests. |
+
+### Verification required before merge
+
+The unchanged final PR head must have focused API/unit security tests plus the repository's full required test/coverage/security checks terminal-success. Predecessor, absent, queued, skipped, or model-only evidence is not acceptance evidence. All current substantive review threads must be obsolete by source proof or resolved after reviewers can inspect the repaired head.

+**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.
+**Prevention:** Always validate webhook URLs against a known blocklist of internal and loopback IP addresses (like `127.x.x.x`, `10.x.x.x`, `169.254.x.x`, `localhost`) to prevent SSRF vulnerabilities.""",

+**Vulnerability:** Webhook registration accepted plaintext HTTP and trusted hostname text before delivery. A DNS name, redirect, IPv6 literal, or legacy persisted row could therefore reach a loopback, private, link-local, metadata, or other special-purpose destination after the registration check.
+**Learning:** Registration-time hostname blocklists are not a network security boundary. OWASP SSRF guidance requires redirect controls, and RFC 6890/IANA special-purpose registries define address semantics. Node's OS-backed DNS lookup must be bound directly to the outbound socket so there is no second unvalidated resolution between policy and connection.
+**Prevention:** Accept HTTPS-only webhook URLs without embedded credentials; distinguish IP literals from DNS labels; validate all DNS answers against standards-derived special-purpose ranges at every delivery attempt; give the validated lookup directly to a non-pooled HTTPS request; never follow redirects; and revalidate legacy persisted webhook rows. Tests use deterministic DNS/transport seams plus a real loopback listener to prove zero internal network access.

-# Product–technical gap baseline
-
-This baseline is derived from the current ScopeWeave source and is updated with executable evidence rather than aspirational status.
-
-## Bounded-context baseline
-
-ScopeWeave currently contains five product responsibilities. **Planning** is the core subdomain and owns projects, task structures, revisions, baselines, schedule data, and optimistic-concurrency invariants. **Workspace Access** is a supporting subdomain and owns organizations, membership, invitations, OIDC, personal access tokens, and authorization. **Integration Delivery** is a supporting subdomain and owns webhook registration, signed-event delivery, retry outcomes, and its outbound-network security policy. **Commercial Entitlement** is a supporting subdomain and owns plans, usage limits, and checkout. **Operational Telemetry** is a generic subdomain and owns request/delivery metrics and operational logs; it is not an authoritative audit or domain-event store.
-
-The Integration Delivery context must depend on a narrow outbound-network adapter rather than embedding DNS/TLS/HTTP policy in Hono route orchestration. Persisted webhook facts remain owned by ScopeWeave; socket selection, DNS resolution, TLS, redirect policy, and timeout behavior belong to the delivery adapter. External network behavior is an anti-corruption boundary: DNS answers or HTTP redirect targets never become trusted domain facts merely because a webhook record was previously accepted.
-
-## Current security gap: outbound webhook SSRF
-
-| Evidence | Status | Acceptance contract |
-| --- | --- | --- |
-| PR #649 original head `ce31e62667cb3a3b7d0deb79c5464952f27dd63c` added registration-time hostname prefix checks only. | FAIL | Registration accepts HTTPS only, rejects credentials/local/special-purpose literal addresses, and does not mistake ordinary DNS labels for IP literals. |
-| Exact-head production-boundary RED introduced on `e84c47c95ef86da416e361704c8b89675227fcf6`. | RED | A pre-existing persisted loopback webhook must receive zero network requests; the failed delivery must be recorded and stay within the bounded retry contract. |
-| Current reviewers identified DNS rebinding/resolution, IPv6, redirects, plaintext HTTP, public numeric-looking hostname false positives, and nondeterministic external-network smoke tests. | OPEN until GREEN | Every delivery attempt re-resolves through the operating-system resolver at the socket boundary, rejects any non-public answer, pins the connection to validated answers, disables redirect following, preserves TLS verification, and uses deterministic network seams in tests. |
-
-### Verification required before merge
-
-The unchanged final PR head must have focused API/unit security tests plus the repository's full required test/coverage/security checks terminal-success. Predecessor, absent, queued, skipped, or model-only evidence is not acceptance evidence. All current substantive review threads must be obsolete by source proof or resolved after reviewers can inspect the repaired head.

-**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.
-**Prevention:** Always validate webhook URLs against a known blocklist of internal and loopback IP addresses (like `127.x.x.x`, `10.x.x.x`, `169.254.x.x`, `localhost`) to prevent SSRF vulnerabilities.""",

-**Vulnerability:** Webhook registration accepted plaintext HTTP and trusted hostname text before delivery. A DNS name, redirect, IPv6 literal, or legacy persisted row could therefore reach a loopback, private, link-local, metadata, or other special-purpose destination after the registration check.
-**Learning:** Registration-time hostname blocklists are not a network security boundary. OWASP SSRF guidance requires redirect controls, and RFC 6890/IANA special-purpose registries define address semantics. Node's OS-backed DNS lookup must be bound directly to the outbound socket so there is no second unvalidated resolution between policy and connection.
-**Prevention:** Accept HTTPS-only webhook URLs without embedded credentials; distinguish IP literals from DNS labels; validate all DNS answers against standards-derived special-purpose ranges at every delivery attempt; give the validated lookup directly to a non-pooled HTTPS request; never follow redirects; and revalidate legacy persisted webhook rows. Tests use deterministic DNS/transport seams plus a real loopback listener to prove zero internal network access.

 **Vulnerability:** The backend CSV export for audit logs neutralized `=`, `+`, `-`, and `@` but failed to neutralize `|` (pipe) characters, allowing potential DDE (Dynamic Data Exchange) injection if exported logs were opened in spreadsheet software.
 **Learning:** Spreadsheet formula defenses must cover all command-style prefixes including `|` across all CSV export boundaries, both frontend and backend.
 **Prevention:** Update the sanitization regex in the backend export function to `/^[=+\-@|]/` so that all potentially executable spreadsheet payloads are prefixed with a single quote.
-## 2026-09-01 - Prevent SSRF via webhook URLs
-**Vulnerability:** The `/api/orgs/:id/webhooks` POST endpoint accepted any valid HTTP/HTTPS URL, including internal IP addresses and loopback domains (`127.0.0.1`, `localhost`, etc). This allowed Server-Side Request Forgery (SSRF).
-**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.
-**Prevention:** Always validate webhook URLs against a known blocklist of internal and loopback IP addresses (like `127.x.x.x`, `10.x.x.x`, `169.254.x.x`, `localhost`) to prevent SSRF vulnerabilities.

 **Vulnerability:** The backend CSV export for audit logs neutralized `=`, `+`, `-`, and `@` but failed to neutralize `|` (pipe) characters, allowing potential DDE (Dynamic Data Exchange) injection if exported logs were opened in spreadsheet software.
 **Learning:** Spreadsheet formula defenses must cover all command-style prefixes including `|` across all CSV export boundaries, both frontend and backend.
 **Prevention:** Update the sanitization regex in the backend export function to `/^[=+\-@|]/` so that all potentially executable spreadsheet payloads are prefixed with a single quote.
+## 2026-09-01 - Prevent SSRF via webhook URLs
+**Vulnerability:** The `/api/orgs/:id/webhooks` POST endpoint accepted any valid HTTP/HTTPS URL, including internal IP addresses and loopback domains (`127.0.0.1`, `localhost`, etc). This allowed Server-Side Request Forgery (SSRF).
+**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.
+**Prevention:** Always validate webhook URLs against a known blocklist of internal and loopback IP addresses (like `127.x.x.x`, `10.x.x.x`, `169.254.x.x`, `localhost`) to prevent SSRF vulnerabilities.

 **Vulnerability:** The backend CSV export for audit logs neutralized `=`, `+`, `-`, and `@` but failed to neutralize `|` (pipe) characters, allowing potential DDE (Dynamic Data Exchange) injection if exported logs were opened in spreadsheet software.
 **Learning:** Spreadsheet formula defenses must cover all command-style prefixes including `|` across all CSV export boundaries, both frontend and backend.
 **Prevention:** Update the sanitization regex in the backend export function to `/^[=+\-@|]/` so that all potentially executable spreadsheet payloads are prefixed with a single quote.
-## 2026-09-01 - Prevent SSRF via webhook URLs
-**Vulnerability:** The `/api/orgs/:id/webhooks` POST endpoint accepted any valid HTTP/HTTPS URL, including internal IP addresses and loopback domains (`127.0.0.1`, `localhost`, etc). This allowed Server-Side Request Forgery (SSRF).
-**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.
-**Prevention:** Always validate webhook URLs against a known blocklist of internal and loopback IP addresses (like `127.x.x.x`, `10.x.x.x`, `169.254.x.x`, `localhost`) to prevent SSRF vulnerabilities.

-**Vulnerability:** The `/api/orgs/:id/webhooks` POST endpoint accepted any valid HTTP/HTTPS URL, including internal IP addresses and loopback domains (`127.0.0.1`, `localhost`, etc). This allowed Server-Side Request Forgery (SSRF).
-**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.

Subject: [PATCH 42/50] fix(webhook): isolate IPv4 and IPv6 blocklists to
 prevent false positives

Fixes a bug where sharing a single `net.BlockList` for both IPv4 and IPv6 caused the `::ffff:0:0/96` IPv4-mapped subnet rule to erroneously drop all valid public IPv4 addresses when evaluated with `family: ipv4`. Separates the blocklists into `BLOCKED4` and `BLOCKED6`.

+## 2026-09-06 - BlockList subnet intersection bug for IPv4-mapped IPv6
+
+**Vulnerability:** Node.js `net.BlockList` drops public IPv4 requests completely when the `::ffff:0:0/96` IPv4-mapped subnet is added to a shared `BlockList` tracking both IPv4 and IPv6 families.
+
+**Learning:** When `net.BlockList.check(address, 'ipv4')` evaluates an IPv4 address, if an overlapping or mapped representation exists in the same list instance, it causes a false positive block for valid public IPv4 addresses, undermining availability or causing valid E2E assertions to fail.
+
+**Prevention:** Always isolate IPv4 and IPv6 blocklist definitions into two separate `net.BlockList` instances (`BLOCKED4` and `BLOCKED6`) and select the appropriate instance when validating an IP address family (`family === 4 ? BLOCKED4 : BLOCKED6`).

 **Vulnerability:** The backend CSV export for audit logs neutralized `=`, `+`, `-`, and `@` but failed to neutralize `|` (pipe) characters, allowing potential DDE (Dynamic Data Exchange) injection if exported logs were opened in spreadsheet software.
 **Learning:** Spreadsheet formula defenses must cover all command-style prefixes including `|` across all CSV export boundaries, both frontend and backend.
 **Prevention:** Update the sanitization regex in the backend export function to `/^[=+\-@|]/` so that all potentially executable spreadsheet payloads are prefixed with a single quote.
-## 2026-09-01 - Prevent SSRF via webhook URLs
-**Vulnerability:** The `/api/orgs/:id/webhooks` POST endpoint accepted any valid HTTP/HTTPS URL, including internal IP addresses and loopback domains (`127.0.0.1`, `localhost`, etc). This allowed Server-Side Request Forgery (SSRF).
-**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.
-**Prevention:** Always validate webhook URLs against a known blocklist of internal and loopback IP addresses (like `127.x.x.x`, `10.x.x.x`, `169.254.x.x`, `localhost`) to prevent SSRF vulnerabilities.
-## 2026-09-06 - BlockList subnet intersection bug for IPv4-mapped IPv6
-
-**Vulnerability:** Node.js `net.BlockList` drops public IPv4 requests completely when the `::ffff:0:0/96` IPv4-mapped subnet is added to a shared `BlockList` tracking both IPv4 and IPv6 families.
-
-**Learning:** When `net.BlockList.check(address, 'ipv4')` evaluates an IPv4 address, if an overlapping or mapped representation exists in the same list instance, it causes a false positive block for valid public IPv4 addresses, undermining availability or causing valid E2E assertions to fail.
-
-**Prevention:** Always isolate IPv4 and IPv6 blocklist definitions into two separate `net.BlockList` instances (`BLOCKED4` and `BLOCKED6`) and select the appropriate instance when validating an IP address family (`family === 4 ? BLOCKED4 : BLOCKED6`).

 **Vulnerability:** The backend CSV export for audit logs neutralized `=`, `+`, `-`, and `@` but failed to neutralize `|` (pipe) characters, allowing potential DDE (Dynamic Data Exchange) injection if exported logs were opened in spreadsheet software.
 **Learning:** Spreadsheet formula defenses must cover all command-style prefixes including `|` across all CSV export boundaries, both frontend and backend.
 **Prevention:** Update the sanitization regex in the backend export function to `/^[=+\-@|]/` so that all potentially executable spreadsheet payloads are prefixed with a single quote.
-## 2026-09-01 - Prevent SSRF via webhook URLs
-**Vulnerability:** The `/api/orgs/:id/webhooks` POST endpoint accepted any valid HTTP/HTTPS URL, including internal IP addresses and loopback domains (`127.0.0.1`, `localhost`, etc). This allowed Server-Side Request Forgery (SSRF).
-**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.
-**Prevention:** Always validate webhook URLs against a known blocklist of internal and loopback IP addresses (like `127.x.x.x`, `10.x.x.x`, `169.254.x.x`, `localhost`) to prevent SSRF vulnerabilities.
-## 2026-09-06 - BlockList subnet intersection bug for IPv4-mapped IPv6
-
-**Vulnerability:** Node.js `net.BlockList` drops public IPv4 requests completely when the `::ffff:0:0/96` IPv4-mapped subnet is added to a shared `BlockList` tracking both IPv4 and IPv6 families.
-
-**Learning:** When `net.BlockList.check(address, 'ipv4')` evaluates an IPv4 address, if an overlapping or mapped representation exists in the same list instance, it causes a false positive block for valid public IPv4 addresses, undermining availability or causing valid E2E assertions to fail.
-
-**Prevention:** Always isolate IPv4 and IPv6 blocklist definitions into two separate `net.BlockList` instances (`BLOCKED4` and `BLOCKED6`) and select the appropriate instance when validating an IP address family (`family === 4 ? BLOCKED4 : BLOCKED6`).

 **Vulnerability:** The backend CSV export for audit logs neutralized `=`, `+`, `-`, and `@` but failed to neutralize `|` (pipe) characters, allowing potential DDE (Dynamic Data Exchange) injection if exported logs were opened in spreadsheet software.
 **Learning:** Spreadsheet formula defenses must cover all command-style prefixes including `|` across all CSV export boundaries, both frontend and backend.
 **Prevention:** Update the sanitization regex in the backend export function to `/^[=+\-@|]/` so that all potentially executable spreadsheet payloads are prefixed with a single quote.
-## 2026-09-01 - Prevent SSRF via webhook URLs
-**Vulnerability:** The `/api/orgs/:id/webhooks` POST endpoint accepted any valid HTTP/HTTPS URL, including internal IP addresses and loopback domains (`127.0.0.1`, `localhost`, etc). This allowed Server-Side Request Forgery (SSRF).
-**Learning:** `new URL(urlStr).hostname` should be strictly validated against a blocklist of internal IP ranges and loopback domains before issuing external HTTP requests on behalf of a user. The native `URL` constructor handles various IP format normalizations effectively.
-**Prevention:** Always validate webhook URLs against a known blocklist of internal and loopback IP addresses (like `127.x.x.x`, `10.x.x.x`, `169.254.x.x`, `localhost`) to prevent SSRF vulnerabilities.
-## 2026-09-06 - BlockList subnet intersection bug for IPv4-mapped IPv6
-
-**Vulnerability:** Node.js `net.BlockList` drops public IPv4 requests completely when the `::ffff:0:0/96` IPv4-mapped subnet is added to a shared `BlockList` tracking both IPv4 and IPv6 families.
-
-**Learning:** When `net.BlockList.check(address, 'ipv4')` evaluates an IPv4 address, if an overlapping or mapped representation exists in the same list instance, it causes a false positive block for valid public IPv4 addresses, undermining availability or causing valid E2E assertions to fail.
-
-**Prevention:** Always isolate IPv4 and IPv6 blocklist definitions into two separate `net.BlockList` instances (`BLOCKED4` and `BLOCKED6`) and select the appropriate instance when validating an IP address family (`family === 4 ? BLOCKED4 : BLOCKED6`).
