    CVE-2026-63400

    Published: 30 Oct 2026Last Modified: 8 Nov 2026

    Summary: Coop sessions are not invalidated on password reset

    Details: 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.
