Stored XSS via unchecked template save
Published Jul 13, 2026 · Updated Jul 13, 2026
Stored XSS in TangibleWP Loops & Logic 4.2.3 and earlier allows remote authenticated users to inject scripts through the template editor. The editor-save AJAX action accepts and stores template content without checking the caller's required capability, allowing attacker-supplied markup to reach rendered pages. Subscriber access is sufficient to store the payload; script execution requires another user to load the affected content, exposing data and page integrity in that browser session.
