CVE-2026-64829Network attack vector

Persistent account access via uncleared sessioncode

Published Jul 22, 2026 · Updated Jul 22, 2026

Insufficient session expiration in Question2Answer 1.8.8 and earlier allows attackers to retain account access with an old persistent cookie. The qa_finish_reset_user() forgot-password handler leaves the account's sessioncode unchanged, so pre-reset qa_session cookies remain valid after the password reset. Exploitation requires a previously obtained persistent cookie and grants authenticated access as the affected account.
