CVE-2026-40525
OpenViking: Unauthenticated remote bot control via OpenAPI HTTP routes
Severity by source
Trivy's own label is CRITICAL. Rated critical by GHSA.
Description
OpenViking prior to version 0.3.9 contains an authentication bypass vulnerability in the VikingBot OpenAPI HTTP route surface where the authentication check fails open when the api_key configuration value is unset or empty. Remote attackers with network access to the exposed service can invoke privileged bot-control functionality without providing a valid X-API-Key header, including submitting attacker-controlled prompts, creating or using bot sessions, and accessing downstream tools, integrations, secrets, or data accessible to the bot.
