PYSEC-2026-388 LiteLLM: Authentication Bypass via Host Header Injection

Impact A Host-header parsing flaw in the LiteLLM proxy could, under specific conditions, allow unauthenticated access to protected management routes. The auth layer derived the effective route from request.url.path in litellm/proxy/auth/authutils.py::getrequestroute, which Starlette reconstructs...

PYSEC-2026-467 PraisonAI Browser Server allows unauthenticated WebSocket clients to hijack connected extension sessions

Summary praisonai browser start exposes the browser bridge on 0.0.0.0 by default, and its /ws endpoint accepts websocket clients that omit the Origin header entirely. An unauthenticated network client can connect as a fake controller, send startsession, cause the server to forward startautomation...

PYSEC-2026-287 Authlib JWS JWK Header Injection: Signature Verification Bypass

Description Summary A JWK Header Injection vulnerability in authlib's JWS implementation allows an unauthenticated attacker to forge arbitrary JWT tokens that pass signature verification. When key=None is passed to any JWS deserialization function, the library extracts and uses the cryptographic...

PYSEC-2026-556 Header injection in TurboGears

A vulnerability classified as critical has been found in OnShift TurboGears 1.0.11.10. This affects an unknown part of the file turbogears/controllers.py of the component HTTP Header Handler. The manipulation leads to http response splitting. It is possible to initiate the attack remotely...

PYSEC-2026-361 joserfc has Possible Uncontrolled Resource Consumption Vulnerability Triggered by Logging Arbitrarily Large JWT Token Payloads

Summary The ExceededSizeError exception messages are embedded with non-decoded JWT token parts and may cause Python logging to record an arbitrarily large, forged JWT payload. Details In situations where a misconfigured — or entirely absent — production-grade web server sits in front of a Python...
