CVE-2026-75480
OpenViking Debug Vector Endpoints Multi-tenant Data Exposure
Description

OpenViking debug vector scroll and count endpoints apply only account-level scoping without user-level access controls, allowing authenticated users to read all co-tenant records. Attackers can query these endpoints to retrieve private memories, resources, skills, and secret material belonging to other users in the same account without administrative privileges.

Solution
Implement user-level access controls for all endpoints to enforce proper authorization.
  • Apply user-level access controls to all relevant endpoints.
  • Verify all data access is scoped to the requesting user.
  • Review and harden authentication and authorization mechanisms.
  • Remove debug endpoints if not necessary for production.
