From 29.0.0 until 47.7.4 and 48.5.1, specially crafted markup can trigger cross-site scripting when General HTML Support is enabled and specifically configured to allow object content. Processing that content can execute attacker-controlled JavaScript in a browser context isolated from the origin of the application embedding the editor. This issue is fixed in versions 47.7.4 and 48.5.1.","state":0,"publishedAt":"2026-10-27T19:33:11.074+00:00","modifiedAt":"2026-10-27T19:33:11.074+00:00","affected":[{"ecosystem":"Vendor product","name":"ckeditor5","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ckeditor\",\n                    \"product\": \"ckeditor5\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 29.0.0, < 47.7.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 48.0.0, < 48.5.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","score":3.1,"severity":"LOW"}],"references":["https://github.com/ckeditor/ckeditor5/security/advisories/GHSA-v6mg-96c6-gmpq","https://github.com/ckeditor/ckeditor5/commit/4d9c5bb34f63cd956d15ccafbe584e14280c86a0","https://github.com/ckeditor/ckeditor5/commit/a750e38635db6a18c5b11599c09f4fd702850423","https://github.com/ckeditor/ckeditor5/releases/tag/v47.7.4","https://github.com/ckeditor/ckeditor5/releases/tag/v48.5.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116687","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116687","identifiers":["CVE-2026-116687"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
