AI-suggested
Until an official fix is available, restrict editor-level access to trusted users only and monitor for suspicious activity related to the MW WP Form plugin. Avoid using the 'memo' parameter for untrusted input. Follow vendor updates for patches or official mitigations.
Description
The MW WP Form WordPress plugin versions up to and including 5.1.3 contain a stored cross-site scripting (XSS) vulnerability via the 'memo' parameter. Authenticated users with editor-level or higher privileges can inject malicious scripts that execute when other users view the affected pages. This occurs because input sanitization and output escaping are insufficient, and WordPress's usual protections do not apply due to how the memo data is stored.
