Contributor-level stored XSS via unsanitized post JavaScript
Published Sep 11, 2026 · Updated Sep 11, 2026
Stored XSS in Enki AI Builder 2.4.1 through 2.7.7 allows remote authenticated users to execute JavaScript in visitors' browsers. The plugin accepts custom JavaScript in page, block, or Site Editor template post metadata under the edit_post capability, then outputs it in a front-end script tag without sanitization. Contributor-level access is sufficient, and execution occurs when any visitor, including an editor or administrator reviewing the content, loads the affected page.
