From 53.0.0 until 53.1.4, the media embed renderer trusts serialized provider or sourceUrl metadata in useMediaState and skips parseMediaUrl protocol validation, allowing a crafted Plate document to set a known video provider while keeping url as a javascript: iframe source that the registry MediaEmbedElement renders directly as an iframe src when a victim opens the document. This issue is fixed in version 53.1.4.","state":0,"publishedAt":"2026-07-08T20:27:58.987+00:00","modifiedAt":"2026-07-09T13:41:00.054+00:00","affected":[{"ecosystem":"Vendor product","name":"plate","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"udecode\",\n                    \"product\": \"plate\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 53.0.0, < 53.1.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/udecode/plate/security/advisories/GHSA-qj6x-xx2h-8hvv","https://github.com/udecode/plate/pull/5014","https://github.com/udecode/plate/commit/6214914ca811adf22d0ad503154494216eed68ba","https://github.com/udecode/plate/releases/tag/v53.1.4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55596","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55596","identifiers":["CVE-2026-55596"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
