Prior to 2.47.11, the sanitizer in src/lib/core.js does not consistently reject namespaced or custom HTML elements, allowing event-handler attributes to remain on crafted elements. When an application renders attacker-controlled editor content and a user interacts with the element, the retained handler can execute script in the application's browser origin, enabling stored cross-site scripting, data exposure, or unauthorized browser-context actions. This issue is fixed in version 2.47.11.","state":0,"publishedAt":"2026-09-23T13:52:56.747+00:00","modifiedAt":"2026-09-24T14:52:33.658+00:00","affected":[{"ecosystem":"Vendor product","name":"suneditor","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"JiHong88\",\n                    \"product\": \"suneditor\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.47.11\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10,"severity":"CRITICAL"}],"references":["https://github.com/JiHong88/suneditor/security/advisories/GHSA-6rf4-v2fh-m6p4","https://github.com/JiHong88/suneditor/issues/1646","https://github.com/JiHong88/suneditor/commit/a94ace269c7102bfb6de58a27a6547bc4eb09045","https://github.com/JiHong88/suneditor/releases/tag/2.47.11"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-59167","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-59167","identifiers":["CVE-2026-59167"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
