Technical description

Question2Answer through 1.8.8 contains a session invalidation vulnerability that allows attackers with a previously obtained remember-me cookie to retain authenticated access by exploiting the forgot-password reset flow's failure to clear the sessioncode field in qa-include/app/users-edit.php. While the normal password-change flow in qa-include/pages/account.php explicitly clears the sessioncode to invalidate persistent qa_session cookies, the forgot-password handler qa_finish_reset_user() omits this step, allowing any valid persistent cookie issued before the reset to continue authenticating the account after the password reset completes.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
