CVE-2026-35615: PraisonAI Has Path Traversal in FileTools

April 6, 2026

The path validation has a critical logic bug: it checks for .. AFTER normpath() has already collapsed all .. sequences. This makes the check completely useless and allows trivial path traversal to any file on the system. The path validation function also does not resolve the symlink wich could potentially cause path traversal.
