docs(security): add email channel and define the framework security model

[bmadcode]

What

Updates SECURITY.md: adds security@bmadcode.com as a reporting channel, replaces the response-time SLA with best-effort language, and adds a Security Model section that states the framework's trust boundary explicitly.

Why

A community member reported that GitHub private vulnerability reporting was disabled on this repo — while SECURITY.md listed GitHub Security Advisories as the preferred channel. Anyone following our documented path hit a 404, leaving "DM a maintainer on Discord" as the only working route.

PVR is now enabled on the repo, so that link resolves. This PR fixes the rest of the policy around it.

The scope change matters for an agent framework specifically: "prompt injection that bypasses intended agent behavior" was in scope, but BMad's entire design is agents reading instructions from markdown and acting on them. Without a stated boundary, nearly any behavior can be framed as prompt injection, and every triage becomes an argument about first principles.

How

• Add security@bmadcode.com as method 2, ahead of Discord DM; ask reporters to keep exploit code out of plaintext email for severe issues
• State plainly that there is no paid bounty program, and that reporters are credited
• Replace 48h/7d/30d targets with best-effort language plus a two-week follow-up nudge framed as a missed notification
• Add a Security Model section: executing instructions from files is the design; the boundary is that content the user did not author or knowingly install must not change agent behavior, and agents must stay within the configured file scope
• Rewrite In Scope around that boundary (untrusted runtime content, permission escapes, secret exposure, installer/update path) and in Out of Scope call out the two big non-issues — installing a module is running its code, and an agent following instructions its author wrote
• Add "vet what you install" as the first user best practice

Testing

Docs-only change. Verified prettier --check SECURITY.md passes and the advisory link now resolves (PVR returns {"enabled": true}).

Greptile Summary

Updates the project security policy to provide an email reporting channel and explicitly define the framework’s trust boundary.

• Adds security@bmadcode.com and clarifies reporter acknowledgment and compensation expectations.
• Replaces fixed response targets with best-effort timelines and follow-up guidance.
• Defines which agent behavior and security-boundary violations are in or out of scope.
• Expands security best practices for users.

Confidence Score: 5/5

The documentation-only change appears safe to merge.

The revised policy consistently describes the intended reporting process and framework trust boundary, and no concrete broken documentation path or contradictory repository requirement was established.

Important Files Changed

Filename	Overview
SECURITY.md	The reporting policy, response expectations, security model, vulnerability scope, and user guidance are coherently revised without an actionable defect established by the repository evidence.

📝 Walkthrough

Walkthrough

The security policy now defines the agent security boundary, expands and clarifies vulnerability scope, updates reporting channels and response expectations, and adds guidance for vetting installed modules.

Changes

Security Policy

Layer / File(s)	Summary
Security boundary and scope SECURITY.md	Defines intended instruction execution, configured file-system limits, in-scope vulnerabilities, out-of-scope issues, and module-vetting guidance.
Vulnerability reporting process SECURITY.md	Adds email and Discord reporting, states that reports are unpaid, updates response expectations, and normalizes the supported-version table.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 1d7d1

The policy clarifies reporting channels and the framework security boundary, but it should explicitly state whether configured tool permissions are part of that boundary because the current wording could make some bypass reports ambiguous. The PR is mergeable with owner awareness or a follow-up clarification.

Define the tool-permission boundary in the Security Model.

The Security Model limits agent actions to the configured file-system scope, but the in-scope list also covers escapes from configured tool-permission limits on Line 75. If tool permissions are part of the intended boundary, name them here. Otherwise, remove the broader scope item. The current mismatch makes triage of tool-permission bypass reports ambiguous.

Proposed wording

-... agent actions should stay within the file system scope the user configured.
+... agent actions should stay within the file-system and tool-permission scope the user configured.

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	The framework's security boundary is this: content that a user did not author or knowingly install should not be able to change agent behavior in ways the user did not intend, and agent actions should stay within the file system scope the user configured.
