CVE-2026-47397 Details
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.
A vulnerability in PraisonAI agents allows for arbitrary file writing. This issue arises from hidden metadata in webpages, which can be exploited to have agents write attacker-controlled content to any path. The vulnerability exists in PraisonAI versions prior to 4.6.40. The root cause is that the 'write_file' function bypasses path validation when the workspace parameter is set to None, which is the default in production. As a result, agents can unintentionally write files to locations specified by the attacker.
Users can update to PraisonAI version 4.6.40 or later, where this vulnerability has been fixed.
