CVE-2026-60104Public exploitNetwork attack vector

Account takeover via mismatched auth-request identity

Published Jul 8, 2026 · Updated Jul 8, 2026

Authorization bypass in Bitwarden Server before 2026.6.0 allows remote authenticated users to take over another member's vault. AuthRequestService.CreateAuthRequestAsync resolves the body email to a user but never compares that user ID with the bearer-token identity, while PostAdminRequest accepts non-admin request types. Exploitation requires a low-privileged member in the victim's SSO and Trusted Device Encryption organization, a known victim device ID, and either owner/admin or victim approval; successful abuse exposes the vault key and a victim-scoped session.
