CVE-2026-44737Public exploitNetwork attack vector

Stored XSS via unescaped page-title rendering

Published May 11, 2026 · Updated May 11, 2026

Stored XSS in Grav Admin Plugin before 1.10.49.5 allows remote authenticated users to execute JavaScript in another administrator's browser. The page move dialog inserts an unescaped page header.title into breadcrumb HTML and a title attribute, so a planted page title becomes executable markup. Exploitation requires admin.pages permission to save the title and active interaction by another administrator, enabling actions or data access in that victim's session.
