Stored XSS via unfiltered TinyMCE event handlers
Published Feb 13, 2020 · Updated Aug 6, 2024
Stored XSS in PrestaShop before 1.4.11 allows remote authenticated users to execute script in other users' browsers via TinyMCE. TinyMCE stores HTML entered in a CMS page without filtering event-handler attributes, so an injected onmouseover handler executes when a victim hovers over the rendered element. A low-privilege Logistician or translator account is sufficient, and exploitation requires another user to view and interact with the stored content, enabling session actions or credential theft.
