AI-suggested
A fix is available in REDAXO version 5.21.5. Users should upgrade to version 5.21.5 or later to ensure that sessions and stay-logged-in keys are properly invalidated upon password changes, preventing attackers from retaining access.
Description
REDAXO versions prior to 5.21.5 have a vulnerability related to insufficient session expiration. This flaw allows attackers who have obtained a user's session ID or stay-logged-in cookie to maintain backend access even after the user changes their password. The stay-logged-in cookie remains valid for up to three months, enabling prolonged unauthorized access.
