Account takeover via recovery-session ownership bypass
Published Jul 29, 2026 · Updated Jul 29, 2026
Incorrect authorization in Ente Museum Server 2.0.34 and earlier allows remote authenticated users to take over accounts via emergency recovery. The approve-recovery handler updates a waiting recovery session by attacker-supplied session ID without verifying that the session belongs to the caller. The attacker must be an accepted emergency contact; the premature ready state bypasses the notice period, enabling password reset and removal of the victim's two-factor protections.
