CVE-2026-64829
CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N
Summary
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.
