CVE-2026-29871
Beifong AI News and Podcast Agent FastAPI Path Traversal Vulnerability
Description
A path traversal vulnerability exists in the awesome-llm-apps project in commit e46690f99c3f08be80a9877fab52acacf7ab8251 (2026-01-19) in the Beifong AI News and Podcast Agent backend in FastAPI backend, stream-audio endpoint, in file routers/podcast_router.py, in function stream_audio. The stream-audio endpoint accepts a user-controlled path parameter that is concatenated into a filesystem path without proper validation or restriction. An unauthenticated remote attacker can exploit this vulnerability to read arbitrary files from the server filesystem, potentially disclosing sensitive information such as configuration files and credentials.
