CVE-2025-0330Network attack vector

Langfuse key disclosure via unredacted proxy errors

Published Mar 20, 2025 · Updated Mar 20, 2025

Information disclosure in Berri AI LiteLLM 1.52.1 and earlier allows remote attackers to read Langfuse API keys via proxy errors. In proxy_server.py, the team-settings error path returns unredacted langfuse_secret and langfuse_public_key values when parsing fails. A reachable proxy configured with Langfuse is required; the exposed keys grant access to the Langfuse project and its stored requests.
