{"id":"GHSA-g68x-vvqq-pvw3","aliases":["CVE-2018-17960"],"title":"Ckeditor XSS Vulnerability","titleSource":"OSV","descriptionSource":"OSV","declaredSeverity":"MODERATE","description":"CKEditor 4.x before 4.11.0 allows user-assisted XSS involving a source-mode paste. It was possible to execute XSS inside the CKEditor source area after persuading the victim to: (i) switch CKEditor to source mode, then (ii) paste a specially crafted HTML code, prepared by the attacker, into the opened CKEditor source area, and (iii) switch back to WYSIWYG mode. Although this is an unlikely scenario, it is recommended to upgrade to the latest editor version.","severity":"medium","score":6.1,"published":"2018-11-21T22:19:50.000Z","modified":"2024-02-16T08:02:21.220Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"npm","name":"ckeditor","sources":[{"name":"OSV · GHSA-g68x-vvqq-pvw3","url":"https://osv.dev/vulnerability/GHSA-g68x-vvqq-pvw3"}],"ranges":[{"events":[{"introduced":"0"},{"fixed":"4.11.0"}],"type":"SEMVER"}],"versions":[],"fixed":["4.11.0"]},{"ecosystem":"Packagist","name":"typo3/cms-core","sources":[{"name":"OSV · GHSA-g68x-vvqq-pvw3","url":"https://osv.dev/vulnerability/GHSA-g68x-vvqq-pvw3"}],"ranges":[{"events":[{"introduced":"8.0.0"},{"fixed":"8.7.21"}],"type":"ECOSYSTEM"}],"versions":["v8.7.10","v8.7.11","v8.7.12","v8.7.13","v8.7.14","v8.7.15","v8.7.16","v8.7.17","v8.7.18","v8.7.19","v8.7.20","v8.7.7","v8.7.8","v8.7.9"],"fixed":["8.7.21"]},{"ecosystem":"Packagist","name":"typo3/cms-core","sources":[{"name":"OSV · GHSA-g68x-vvqq-pvw3","url":"https://osv.dev/vulnerability/GHSA-g68x-vvqq-pvw3"}],"ranges":[{"events":[{"introduced":"9.0.0"},{"fixed":"9.5.2"}],"type":"ECOSYSTEM"}],"versions":["v9.0.0","v9.1.0","v9.2.0","v9.2.1","v9.3.0","v9.3.1","v9.3.2","v9.3.3","v9.4.0","v9.5.0","v9.5.1"],"fixed":["9.5.2"]},{"ecosystem":"Packagist","name":"typo3/cms","sources":[{"name":"OSV · GHSA-g68x-vvqq-pvw3","url":"https://osv.dev/vulnerability/GHSA-g68x-vvqq-pvw3"}],"ranges":[{"events":[{"introduced":"8.0.0"},{"fixed":"8.7.21"}],"type":"ECOSYSTEM"}],"versions":["8.0.0","8.0.1","8.1.0","8.1.1","8.1.2","8.2.0","8.2.1","8.3.0","8.3.1","8.4.0","8.4.1","8.5.0","8.5.1","8.6.0","8.6.1","8.7.0","8.7.1","8.7.2","v8.7.10","v8.7.11","v8.7.12","v8.7.13","v8.7.14","v8.7.15","v8.7.16","v8.7.17","v8.7.18","v8.7.19","v8.7.20","v8.7.3","v8.7.4","v8.7.5","v8.7.6","v8.7.7","v8.7.8","v8.7.9"],"fixed":["8.7.21"]},{"ecosystem":"Packagist","name":"typo3/cms","sources":[{"name":"OSV · GHSA-g68x-vvqq-pvw3","url":"https://osv.dev/vulnerability/GHSA-g68x-vvqq-pvw3"}],"ranges":[{"events":[{"introduced":"9.0.0"},{"fixed":"9.5.2"}],"type":"ECOSYSTEM"}],"versions":["v9.0.0","v9.1.0","v9.2.0","v9.2.1","v9.3.0","v9.3.1","v9.3.2","v9.3.3","v9.4.0","v9.5.0","v9.5.1"],"fixed":["9.5.2"]}],"sourceAffected":[],"references":["https://nvd.nist.gov/vuln/detail/CVE-2018-17960","https://ckeditor.com/blog/CKEditor-4.11-with-emoji-dropdown-and-auto-link-on-typing-released","https://ckeditor.com/cke4/release/CKEditor-4.11.0","https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms-core/CVE-2018-17960.yaml","https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms/CVE-2018-17960.yaml","https://github.com/advisories/GHSA-g68x-vvqq-pvw3","https://typo3.org/security/advisory/typo3-core-sa-2018-005","https://web.archive.org/web/20200227030123/http://www.securityfocus.com/bid/109205","https://www.oracle.com/technetwork/security-advisory/cpujul2019-5072835.html"],"sources":[{"name":"OSV","id":"GHSA-g68x-vvqq-pvw3","modified":"2024-02-16T08:02:21.220386Z","url":"https://osv.dev/vulnerability/GHSA-g68x-vvqq-pvw3"}],"assessments":[{"source":"OSV","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1}],"products":[],"remediation":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T10:50:31.869Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
