CVE-2024-29203: Tiny Tinymce

Medium severity, CVSS 6.1. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Tiny Tinymce: before 6.8.1 (fixed in 6.8.1); from 6.8.2, before 7.0.0 (fixed in 7.0.0)
