What is CVE-2026-35615?

PraisonAI, a multi-agent systems platform, was found to have a vulnerability in its path validation mechanism prior to version 1.5.113. The method _validate_path() incorrectly handles path normalization. Specifically, it calls os.path.normpath(), which eliminates '..' sequences, effectively making any subsequent checks for '../' ineffective. This flaw allows an attacker to exploit the system's file access mechanism, leading to unauthorized traversal to any file within the server's file structure. Users are urged to update to version 1.5.113 or later to mitigate this security risk.

Affected Version(s)

PraisonAI < 4.5.113
