Stored script execution via unescaped shortcode attributes

Published Feb 13, 2023 · Updated Mar 21, 2025

Stored cross-site scripting in Amazon JS 0.10 and earlier allows remote authenticated users to inject scripts through shortcodes. The plugin outputs user-controlled asin, imgsize, and tmpl shortcode attributes into page or post markup without validating or escaping them. Contributor-level access is required to store a payload, and the script executes when another user opens the affected page or post.
