{"id":"UBUNTU-CVE-2026-116675","details":"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.","modified":"2026-10-28T20:17:45.741916901Z","published":"2026-10-27T17:16:00Z","upstream":["CVE-2026-116675"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-116675"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-116675"},{"type":"REPORT","url":"https://github.com/tinymce/tinymce/commit/bd1ab5ef024c648c3f9c0b409e54a6c227c7d8a2"},{"type":"REPORT","url":"https://github.com/tinymce/tinymce/releases/tag/8.9.3"},{"type":"REPORT","url":"https://github.com/tinymce/tinymce/security/advisories/GHSA-mf2p-h6hf-fcwm"},{"type":"REPORT","url":"https://www.tiny.cloud/docs/tinymce/7/7.9.4-release-notes/#overview"},{"type":"REPORT","url":"https://www.tiny.cloud/docs/tinymce/latest/8.9.3-release-notes/#overview"}],"affected":[{"package":{"name":"tinymce","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/tinymce?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.8+dfsg0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"tinymce","binary_version":"3.4.8+dfsg0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116675.json"}},{"package":{"name":"tinymce","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/tinymce?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.8+dfsg0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"tinymce","binary_version":"3.4.8+dfsg0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116675.json"}},{"package":{"name":"tinymce","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/tinymce?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.8+dfsg0-2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.4.8+dfsg0-2","binary_name":"tinymce"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-116675.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
