CVE-2026-117558high8.5
ai-sdlc MCP Server through 0.31.2 Command Injection via check_issue and check_pr_status
The advisory, in context
The ai-sdlc plugin MCP server through 0.31.2 contains an OS command injection vulnerability that allows attackers to execute commands by supplying shell metacharacters in the repo argument. The unvalidated repo value is interpolated into gh issue view or gh pr view commands run via execSync(), letting prompt-injected agents execute commands as the MCP server user.
