{"cve":"CVE-2025-58064","nvd":{"published":"2025-09-04T10:42:32.343","modified":"2026-06-17T09:43:51.800","status":"Deferred","description":"CKEditor 5 is a modern JavaScript rich-text editor with an MVC architecture. ckeditor5 and ckeditor5-clipboard versions 46.0.0 through 46.0.2 and 44.2.0 through 45.2.1 contain a Cross-Site Scripting (XSS) vulnerability. Ability to exploit could be triggered by a specific user action (leading to unauthorized JavaScript code execution) if the attacker managed to insert a malicious content into the editor, which might happen with a very specific editor configuration. This vulnerability affects installations where the editor configuration meets one of the following criteria: the HTML embed plugin is enabled, or there is a custom plugin introducing an editable element where view RawElement is enabled. This issue is fixed in versions 45.2.2 and 46.0.3 of both ckeditor5 and ckeditor5-clipboard.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:N/SI:L/SA:N","score":2.3},"cvss_v3":null,"cwes":["CWE-79"],"references":["https://github.com/ckeditor/ckeditor5/commit/b210e90c6cf84e662ef6c7daf93a92355a961bf2","https://github.com/ckeditor/ckeditor5/security/advisories/GHSA-x9gp-vjh6-3wv6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:08:41.295252406+00:00"},"epss":{"cve":"CVE-2025-58064","score":0.00417,"percentile":0.36089,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-x9gp-vjh6-3wv6","url":"https://osv.dev/vulnerability/GHSA-x9gp-vjh6-3wv6","summary":"CKEditor 5 cross-site scripting (XSS) vulnerability in the clipboard package","modified":"2025-09-04T13:51:52Z","packages":[{"ecosystem":"npm","name":"ckeditor5","purl":"pkg:npm/ckeditor5","ranges":[">=46.0.0 <46.0.3"],"fixed":["46.0.3"]},{"ecosystem":"npm","name":"@ckeditor/ckeditor5-clipboard","purl":"pkg:npm/%40ckeditor/ckeditor5-clipboard","ranges":[">=44.2.0 <45.2.2"],"fixed":["45.2.2"]},{"ecosystem":"npm","name":"ckeditor5","purl":"pkg:npm/ckeditor5","ranges":[">=44.2.0 <45.2.2"],"fixed":["45.2.2"]},{"ecosystem":"npm","name":"@ckeditor/ckeditor5-clipboard","purl":"pkg:npm/%40ckeditor/ckeditor5-clipboard","ranges":[">=46.0.0 <46.0.3"],"fixed":["46.0.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
