Stored script execution via unescaped snippet preview

Published Feb 24, 2023 · Updated Apr 8, 2026

Stored XSS in Awesome Motive All in One SEO 4.2.9 and earlier allows remote authenticated users to execute scripts through post fields. The post editor passes an unescaped submitted title, meta description, or related field into a DOM-generated snippet preview, where stored markup becomes executable. Contributor-level access is sufficient, and the payload runs in an authenticated user's browser when that user edits or reviews the affected post or page.
