CVE-2026-18986
Description
The Entity Browser module allows you to select entities from entity reference fields using a custom entity browser widget. The module doesn't sufficiently sanitize the the tab titles, resulting in a stored cross-site scripting (XSS) vulnerability. The vulnerability is mitigated by the fact an attacker must be able to insert HTML with specific attributes on a page that is displaying an entity browser.
