Summary

The ai-sdlc plugin MCP server through 0.31.2 contains an OS command injection vulnerability. Attackers can execute commands by supplying shell metacharacters in the repo argument, which is interpolated into gh issue view or gh pr view commands run via execSync().

Risk Assessment

Prompt-injected agents can execute arbitrary commands as the MCP server user, potentially leading to system compromise or repository access.

Recommendation

Update the ai-sdlc plugin to a patched version or restrict access to the MCP server. Validate the repo argument before passing it to gh commands.
