What is CVE-2026-10089?

The Insert Pages plugin for WordPress allows attackers with author-level access or higher to exploit a stored cross-site scripting vulnerability. This occurs through insufficient output escaping of post custom field keys when rendering pages that use the shortcode [insert page='ID' display='all']. The vulnerability allows for the injection of malicious web scripts, which could execute for any user visiting the affected pages, potentially compromising user security and site integrity.
