Contributor-level stored XSS via shortcode attributes
Published Mar 27, 2024 · Updated Apr 28, 2026
Stored XSS in Crypto Converter Widget 1.8.4 and earlier allows remote authenticated users to inject scripts through shortcode attributes. The shortcode handler neither sanitizes user-supplied attributes nor escapes them before embedding them in page output. Contributor-level access permits payload storage, and the scripts execute when visitors open an affected page.
