Stored XSS via unescaped shortcode attributes

Published Feb 13, 2023 · Updated Mar 20, 2025

Stored XSS in Modern Tribe GigPress before 2.3.28 allows remote authenticated users to inject scripts through shortcode attributes. The shortcode renderer returns user-supplied attributes in page or post output without validation or context-appropriate escaping. Contributor-level access is required to store a payload, and the script executes in the site origin when another user opens the injected page.
