Coop sessions are not invalidated on password reset

Impact

Coop versions prior to 1.0.2 have a weakness where sessions are not invalidated after a password reset, allowing an attacker with a password and established session to retain access until the session expires. The issue is fixed in version 1.0.2. An attacker must have acquired a password and established a session to exploit this weakness.

Original source description

Coop is an open source review and moderation tool from ROOST. Prior to 1.0.2, resetPasswordForToken updates the password row without invalidating database-backed sessions. An attacker who has acquired a password and established a session retains access even after the legitimate user resets the password, leaving the compromised account under attacker control until the session expires at its 30-day maximum age. This issue is fixed in version 1.0.2.
