Contributor-level stored XSS via unescaped shortcode attributes
Published Feb 6, 2023 · Updated Mar 25, 2025
Stored XSS in WC Vendors Marketplace before 2.4.5 allows remote authenticated users to run scripts through crafted shortcode attributes. Its shortcode rendering path returns unvalidated, unescaped attribute values in embedded page or post output, causing browsers to interpret attacker-controlled markup as code. Contributor-level access is required to store the payload, and another user must view the affected page or post to execute it.
