CVE-2026-34999

OpenViking versions 0.2.5 prior to 0.2.14 contain a missing authentication vulnerability in the bot proxy router that allows remote unauthenticated attackers to access protected bot proxy functionality by sending requests to the POST /bot/v1/chat and POST /bot/v1/chat/stream endpoints. Attackers can bypass authentication checks and interact directly with the upstream bot backend through the OpenViking proxy without providing valid credentials.

Summary		(es) Versiones de OpenViking 0.2.5 anteriores a la 0.2.14 contienen una vulnerabilidad de autenticación ausente en el router proxy del bot que permite a atacantes remotos no autenticados acceder a la funcionalidad protegida del proxy del bot enviando solicitudes a los endpoints POST /bot/v1/chat y POST /bot/v1/chat/stream. Los atacantes pueden eludir las comprobaciones de autenticación e interactuar directamente con el backend del bot ascendente a través del proxy de OpenViking sin proporcionar credenciales válidas.
