CVE-2026-75480Public exploitNetwork attack vectorHinoki check available

Authenticated cross-tenant data exposure via debug endpoints

Published Aug 17, 2026 · Updated Aug 18, 2026

Incorrect authorization in Volcengine OpenViking 0.4.14 and earlier allows remote authenticated users to read co-tenant context records via debug endpoints. The /api/v1/debug/vector/scroll and /api/v1/debug/vector/count paths paginate raw vector-store records through _SingleAccountBackend, which adds only an account_id filter and omits per-user namespace scoping and _is_accessible checks used by normal search and find flows. Any non-admin user with valid API access to the debug interface can enumerate other users' memories, resources, skills, and stored secrets within the same account.
