Scanner confirmation: trivy rule CVE-2026-9277 flagged this pattern.

Changes

• docs-site/package.json
• docs-site/package-lock.json

Behavior Preservation

The change is scoped to 2 files on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.

---

This change addresses a pattern flagged by static analysis. The code path handles user-influenced input and the fix reduces the attack surface against both manual and automated exploitation.

Code review — /code-review --fix

Thanks for this. The change is correct and better than the description says — but the description is wrong in a way worth fixing, and there is a collision with your other PR that needs handling before both can land.

Rebased onto main (this was behind several merges) and approved the workflow run so CI could execute; no code changes were needed.

The fix is right — and does more than claimed

Title and body say 1.8.4. The diff actually pins 1.9.0. That is the better version, because there are two advisories in play, not one:

Advisory	Severity	Vulnerable	Patched
GHSA-w7jw-789q-3m8p / CVE-2026-9277	CRITICAL	>= 1.1.0, <= 1.8.3	1.8.4
GHSA-395f-4hp3-45gv / CVE-2026-13311	HIGH	<= 1.8.4	1.9.0

Pinning to the advertised 1.8.4 would have left the second one open. Please correct the title and body — a security PR whose stated target does not match its diff is the kind of thing that gets waved through on the description alone.

The overrides block is doing real work

Worth stating explicitly, because it looks like belt-and-braces and is not: concurrently (a devDependency) pins shell-quote at exactly 1.8.3, so bumping the lockfile entry alone would be reverted by the next resolution. With the override there is exactly one copy in the tree:

node_modules/shell-quote @ 1.9.0

Verified concurrently -> 1.8.3 and launch-editor -> ^1.8.3 both resolve through it.

Supply-chain verification

Since this is a lockfile change from outside the org, I checked the artifacts rather than the description:

• shell-quote@1.9.0 exists on the registry and the integrity hash in the lockfile matches the registry's byte for byte
• resolved points at registry.npmjs.org, not a substituted host
• npm ci --dry-run resolves cleanly; npm install --package-lock-only produces no further diff, so the lockfile is internally consistent despite npm not recording the overrides block in packages[""]
• the @docusaurus/theme-mermaid line going ^3.9.2 → 3.9.2 is a correction: package.json already pinned it exactly and the lockfile had drifted

Blocking on the other PR: #226 will clobber this

#226 adds its own overrides block at the same position in the same file:

"overrides": { "websocket-driver": "0.7.5" }

Whichever lands second must merge the two keys, not replace the block. A naive conflict resolution that takes one side wholesale silently un-pins the other package and reopens a CRITICAL advisory, with a green build and no diff to notice it in. I am landing this one first and will resolve #226's rebase so both pins survive.

Out of scope, noted

docs-site still carries 58 advisories after this change. websocket-driver is #226; the rest are the webpack-dev-server tree and are dev-only.
