Authenticated arbitrary file write via unsanitized user ID
Published Aug 25, 2026 · Updated Aug 25, 2026
Path traversal in PraisonAI before 1.6.58 allows remote authenticated users to write JSON files outside the memory directory. FileMemory.init joins the caller-controlled user_id directly to base_path without validation or containment checks, then creates directories and JSON memory files beneath the resulting path. Reachability requires control of a file-memory user ID, directly or through an agent configuration or jobs API; writes are limited to process-writable locations and JSON-formatted memory content.
