Contributor-level stored XSS via unescaped shortcode attribute
Published Feb 13, 2023 · Updated Mar 21, 2025
Stored XSS in WordPress Go Go Lightbox Gallery before 0.9.5 allows remote authenticated users to inject scripts through a gallery shortcode. The shortcode handler returns the user-supplied class attribute in page output without validating or escaping it. Contributor-level access is sufficient to store the payload, which executes in a visitor's browser whenever the injected page is viewed.
