Gogs: Stored XSS in branch and wiki views through author and committer names

@@ -0,0 +1,11 @@
+Analyze and help fix the GitHub Security Advisory (GHSA) at: $ARGUMENTS
+
+Steps:
+1. Fetch the GHSA page using `gh api repos/gogs/gogs/security-advisories` and understand the vulnerability details (description, severity, affected versions, CWE).
+2. Verify the reported vulnerability actually exists, and why.
+3. Identify the affected code in this repository.
+4. Propose a fix with a clear explanation of the root cause and how the fix addresses it. Check for prior art in the codebase to stay consistent with existing patterns.
+5. Implement the fix. Only add tests when there is something meaningful to test at our layer.
+6. Run all the usual build and test commands.
+7. Create a branch named after the GHSA ID, commit, and push.
+8. Create a pull request with a proper title and description, do not reveal too much detail and link the GHSA.
