CVE-2026-35615 PraisonAI has a Path Traversal in FileTools

What is CVE-2026-35615?

CVE-2026-35615 is a critical path traversal vulnerability in MervinPraison PraisonAI, published on 7 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

PraisonAI is a multi-agent teams system. Prior to 1.5.113, _validate_path() calls os.path.normpath() first, which collapses .. sequences, then checks for '..' in normalized. Since .. is already collapsed, the check always passes. This makes the check completely useless and allows trivial path traversal to any file on the system. This vulnerability is fixed in 1.5.113.

Weakness: CWE-22
