Description OSIDB Bzimport 2026-05-28 16:02:14 UTC 
TinyMCE is an open source rich text editor. From 6.8.0 to before 7.1.0, TinyMCE contains an XSS vulnerability caused by improper SVG namespace scope handling in the sanitizer. A crafted payload using nested elements can bypass attribute sanitization and execute arbitrary JavaScript. This vulnerability is fixed in 7.1.0.
