CVE-2026-116675
TinyMCE is an open source rich text editor. From 7.9.3 until 7.9.4 and from 8.5.1 until 8.9.3, the media plugin creates elements crafted through data-mce-object
TinyMCE is an open source rich text editor. From 7.9.3 until 7.9.4 and from 8.5.1 until 8.9.3, the media plugin creates elements crafted through data-mce-object in the active document before sanitization. Those elements can execute malicious scripts during processing, resulting in stored cross-site scripting for users with the media plugin enabled. This issue is fixed in versions 8.9.3 and 7.9.4.
