CVE-2026-47397

HIGH

PraisonAI has an Arbitrary File Write in Python API

Title source: cna
STIX 2.1

Description

PraisonAI is a multi-agent teams system. Prior to version 4.6.40, hidden metadata in a webpage causes PraisonAI agents to write attacker-controlled content to arbitrary paths. `write_file` skips path validation when `workspace=None` (always `None` in production). Version 4.6.40 fixes the issue.
