CVE-2026-34999
OpenViking 0.2.5 < 0.2.14 Bot Proxy Endpoints Allow Unauthenticated Access
Description

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.
