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.","cvssScore":3.1,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ckeditor/ckeditor5/commit/4d9c5bb34f63cd956d15ccafbe584e14280c86a0","tags":[]},{"url":"https://github.com/ckeditor/ckeditor5/commit/a750e38635db6a18c5b11599c09f4fd702850423","tags":[]},{"url":"https://github.com/ckeditor/ckeditor5/releases/tag/v47.7.4","tags":[]},{"url":"https://github.com/ckeditor/ckeditor5/releases/tag/v48.5.1","tags":[]},{"url":"https://github.com/ckeditor/ckeditor5/security/advisories/GHSA-v6mg-96c6-gmpq","tags":[]}],"exploitRefs":[{"url":"https://github.com/ckeditor/ckeditor5/commit/4d9c5bb34f63cd956d15ccafbe584e14280c86a0","tags":[]},{"url":"https://github.com/ckeditor/ckeditor5/commit/a750e38635db6a18c5b11599c09f4fd702850423","tags":[]},{"url":"https://github.com/ckeditor/ckeditor5/releases/tag/v47.7.4","tags":[]},{"url":"https://github.com/ckeditor/ckeditor5/releases/tag/v48.5.1","tags":[]},{"url":"https://github.com/ckeditor/ckeditor5/security/advisories/GHSA-v6mg-96c6-gmpq","tags":[]}],"hasPoc":true,"ai":null}
