Stored XSS via campaign reward description
Published Dec 11, 2023 · Updated Aug 2, 2024
Stored XSS in Themeum WP Crowdfunding before 2.1.8 allows remote authenticated users to inject script through reward descriptions. The campaign form stores a script payload entered in a reward description without sanitizing or escaping it, then renders it in the campaign list. Administrator access is required, and opening the published campaign list executes the stored script in the viewer’s browser even when unfiltered_html is disabled.
