Users should monitor the vendor's advisory for updates. Until a fix is released, restrict administrator access to trusted users only and avoid visiting the plugin's settings page unnecessarily. Consider disabling or removing the plugin if possible to mitigate risk.
Description
The Sentence To SEO WordPress plugin contains a stored cross-site scripting (XSS) vulnerability in the 'Permanent keywords' field due to improper input sanitization and output escaping. Authenticated users with administrator-level privileges can inject arbitrary HTML or JavaScript code that executes when the plugin's settings page is viewed. This vulnerability affects all versions up to and including 1.0. No official patch or remediation guidance is currently available.
