The Open eClass platform (formerly known as GUnet eClass) is a complete course management system. Prior to version 4.2, failure to invalidate active user sessions after a password change allows existing session tokens to remain valid, potentially enabling unauthorized continued access to user accounts. This issue has been patched in version 4.2.
