GSD-2024-29203

Vulnerability from gsd - Updated: 2024-04-02 05:02
Details
TinyMCE is an open source rich text editor. A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s content insertion code. This allowed `iframe` elements containing malicious code to execute when inserted into the editor. These `iframe` elements are restricted in their permissions by same-origin browser protections, but could still trigger operations such as downloading of malicious assets. This vulnerability is fixed in 6.8.1.
