CVE-2026-35615 | BDVDB-2026-325367 Detail

MervinPraisonPraisonAI

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.

Impact#

Per CVSS v4.0: confidentiality impact high, integrity impact none, availability impact none. Attack vector: network.

Weaknesses#
