{"id":"CVE-2025-58064","aliases":["GHSA-x9gp-vjh6-3wv6"],"url":"https://o3.security/vulnerability/CVE-2025-58064","summary":"CKEditor is susceptible to Cross-Site Scripting (XSS) through its clipboard package","details":"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.","published":"2025-09-03T22:02:53.296Z","modified":"2026-07-15T01:49:05.581136952Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"ckeditor5","fixedVersion":"46.0.3"},{"ecosystem":"npm","name":"@ckeditor/ckeditor5-clipboard","fixedVersion":"45.2.2"},{"ecosystem":"npm","name":"ckeditor5","fixedVersion":"45.2.2"},{"ecosystem":"npm","name":"@ckeditor/ckeditor5-clipboard","fixedVersion":"46.0.3"}],"fix":{"url":"https://github.com/ckeditor/ckeditor5/commit/b210e90c6cf84e662ef6c7daf93a92355a961bf2","label":"ckeditor/ckeditor5@b210e90"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/58xxx/CVE-2025-58064.json"},{"type":"ADVISORY","url":"https://github.com/ckeditor/ckeditor5/security/advisories/GHSA-x9gp-vjh6-3wv6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-58064"},{"type":"FIX","url":"https://github.com/ckeditor/ckeditor5/commit/b210e90c6cf84e662ef6c7daf93a92355a961bf2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:05.581136952Z"}}
