CVE-2026-117558 Details
Description
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.
A command injection vulnerability has been identified in the AI-SDLC plugin's MCP server, affecting versions through 0.31.2. The issue arises in the 'check_issue' and 'check_pr_status' tools, where the 'repo' parameter is directly interpolated into shell commands executed with 'execSync()'. This lack of validation allows for arbitrary command execution on the host system.
The vulnerability has been fixed in version 0.31.2 of the AI-SDLC plugin. Users should update to this version. The fix involves changing the 'check_issue' and 'check_pr_status' tools to use 'execFileSync' with argument arrays, which does not invoke a shell, thereby preventing command injection. Input validation has also been added to ensure the 'repo' parameter is in the correct format before any command is executed.
