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.","state":0,"publishedAt":"2026-10-27T16:47:01.183+00:00","modifiedAt":"2026-10-28T16:15:12.999+00:00","affected":[{"ecosystem":"Vendor product","name":"tinymce","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tinymce\",\n                    \"product\": \"tinymce\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 8.5.1, < 8.9.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 7.9.3, < 7.9.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"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","score":8.5,"severity":"HIGH"}],"references":["https://github.com/tinymce/tinymce/security/advisories/GHSA-mf2p-h6hf-fcwm","https://github.com/tinymce/tinymce/commit/bd1ab5ef024c648c3f9c0b409e54a6c227c7d8a2","https://github.com/tinymce/tinymce/releases/tag/8.9.3","https://www.tiny.cloud/docs/tinymce/7/7.9.4-release-notes/#overview","https://www.tiny.cloud/docs/tinymce/latest/8.9.3-release-notes/#overview"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116675","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116675","identifiers":["CVE-2026-116675"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
