A theoretical vulnerability has been identified in CKEditor 4.22 (and above). In a highly unlikely scenario where an attacker gains control over the https://cke4.ckeditor.com domain, they could potentially execute an attack on CKEditor 4 instances. The issue impacts only editor instances with enabled version notifications. Please note that this feature is disabled by default in all CKEditor 4 LTS versions. Therefore, if you use CKEditor 4 LTS, it is highly unlikely that you are affected by this vulnerability. If you are unsure, please contact us. The fix is available in version 4.25.0-lts.","published":"2024-08-21T15:17:24.176Z","modified":"2026-07-15T01:49:19.446583979Z","cvss":{"score":3.1,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"ckeditor4","fixedVersion":"4.25.0"}],"fix":{"url":"https://github.com/ckeditor/ckeditor4/commit/b5069c9cb769ea22eae1cbd7200f22b1cf2e3a7f","label":"ckeditor/ckeditor4@b5069c9"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/43xxx/CVE-2024-43411.json"},{"type":"ADVISORY","url":"https://github.com/ckeditor/ckeditor4/security/advisories/GHSA-6v96-m24v-f58j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-43411"},{"type":"FIX","url":"https://github.com/ckeditor/ckeditor4/commit/b5069c9cb769ea22eae1cbd7200f22b1cf2e3a7f"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:19.446583979Z"}}
