In affected versions of WordPress, a password reset link emailed to a user does not expire upon changing the user password. Access would be needed to the email account of the user by a malicious party for successful execution. This has been patched in version 5.4.1, along with all the previously affected versions via a minor release (5.3.3, 5.2.6, 5.1.5, 5.0.9, 4.9.14, 4.8.13, 4.7.17, 4.6.18, 4.5.21, 4.4.22, 4.3.23, 4.2.27, 4.1.30, 4.0.30, 3.9.31, 3.8.33, 3.7.33).

path/wp-includes/class-wp-query.php
  • A Google dork targeting vulnerable WordPress installations can be used to identify exposed targets; monitor for reconnaissance queries against /wp-includes/class-wp-query.php
  • The exploit abuses the WordPress password reset flow: an attacker with access to the victim's email can reuse a previously issued password reset link even after the user has changed their password. Detect repeated or delayed use of password reset tokens (wp-login.php?action=rp) after a password change event.
  • The exploit script performs an HTTP GET request to the stale password reset link to check if it is still valid (HTTP 200 response). Monitor for GET requests to WordPress password reset URLs (?action=rp&key=...) originating from unusual IPs or after a password change has already occurred.
  • ·Exploitation requires the attacker to have access to the victim's email account in order to obtain the password reset link; this is a prerequisite, not a network-reachable condition.
  • ·The vulnerability is patched in WordPress 5.4.1 and all listed prior minor releases. Unpatched versions spanning from 3.7.x through 5.4.0 are affected.
