Stored XSS via unsanitized TinyMCE block content
Published Aug 5, 2024 · Updated Aug 7, 2024
Stored XSS in the Ditty TinyMCE block before 3.1.45 allows remote authenticated users to inject scripts into Ditty content. The block saves user-supplied main-text HTML without sufficient sanitization or output escaping, so an image error-handler payload persists and executes when the Ditty page loads. Contributor-level access is sufficient; execution occurs in a visitor's browser and can act with that visitor's WordPress privileges.
