Stored XSS via unsanitized Block Editor JSON
Published Nov 13, 2025 · Updated Nov 13, 2025
Stored XSS in the Block Editor in Directus before 11.13.0 allows remote authenticated users to execute JavaScript in viewers' browsers. The interface copied attacker-controlled strings from nested EditorJS block data without HTML sanitization, allowing an iframe srcdoc value to load an uploaded script despite CSP. Exploitation requires upload-files and edit-item permissions plus a viewer opening the stored content, enabling session theft, phishing, or actions with the viewer's privileges.
