GHSA-9qhq-v63v-fv3j: Incomplete fix for CVE-2026-34935: Command Injection in MervinPraison/PraisonAI

April 17, 2026

The fix for PraisonAI’s MCP command handling does not add a command allowlist or argument validation to parse_mcp_command(), allowing arbitrary executables like bash, python, or /bin/sh with inline code execution flags to pass through to subprocess execution.
