Description
Bitwarden Server before 2026.6.0 does not verify that the email in a POST /auth-requests/admin-request body belongs to the authenticated caller, allowing a low-privileged organization member to obtain another user's vault key and a victim-scoped access token by creating a Trusted Device Encryption authentication request, bound to an attacker-controlled public key, that is readable from an unauthenticated endpoint once approved resulting in disclosure of the victim's vault key and account takeover.
