From b917e3f280b5cb68524e8246c341e6693f261cba Mon Sep 17 00:00:00 2001 From: Ahmed Abushagur Date: Thu, 23 Apr 2026 23:46:13 -0700 Subject: [PATCH] fix(security): add collaborator filter to all agent prompts (#3351) Raw `gh issue list` / `gh pr list` in agent prompts bypassed the bash collaborator gate, letting Claude read non-collaborator issues (potential prompt injection vector). All prompts now pipe through a jq filter using the cached collaborator list. - Added collaborator gate section to _shared-rules.md - Patched 10 prompt files with inline jq collaborator filter - High-risk: community-coordinator, security-issue-checker, qa-record-keeper, security-scanner (read issue bodies) - Lower-risk: PR list commands in refactor/security prompts Co-authored-by: Claude Opus 4.6 (1M context) --- .../skills/setup-agent-team/_shared-rules.md | 24 ++++++++++++++++++- .../setup-agent-team/refactor-issue-prompt.md | 4 ++-- .../setup-agent-team/refactor-team-prompt.md | 1 + .../security-review-all-prompt.md | 2 +- .../setup-agent-team/security-scan-prompt.md | 2 +- .../security-team-building-prompt.md | 2 +- .../teammates/qa-record-keeper.md | 2 +- .../refactor-community-coordinator.md | 2 +- .../teammates/refactor-pr-maintainer.md | 2 +- .../teammates/security-issue-checker.md | 2 +- .../teammates/security-scanner.md | 2 +- 11 files changed, 34 insertions(+), 11 deletions(-) diff --git a/.claude/skills/setup-agent-team/_shared-rules.md b/.claude/skills/setup-agent-team/_shared-rules.md index d5e05d95..1283f580 100644 --- a/.claude/skills/setup-agent-team/_shared-rules.md +++ b/.claude/skills/setup-agent-team/_shared-rules.md @@ -16,9 +16,31 @@ Does NOT apply to labeled issues or mandated tasks — those must be done.
