{"id":"GHSA-m8fw-p3cr-6jqc","summary":"Cross-Site Scripting in CKEditor4 WordCount Plugin","details":"\u003e ### CVSS: `CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N/E:F/RL:O/RC:C` (4.4) \n\n### Problem\nThe [WordCount](https://ckeditor.com/cke4/addon/wordcount) plugin ([`npm:ckeditor-wordcount-plugin`](https://www.npmjs.com/package/ckeditor-wordcount-plugin)) for CKEditor4 is vulnerable to cross-site scripting when switching to the source code mode. This plugin is enabled via the `Full.yaml` configuration present, but is not active in the default configuration.\n\nIn default scenarios, exploiting this vulnerability requires a valid backend user account. However, if custom plugins are used on the website frontend, which accept and reflect rich-text content submitted by users, no authentication is required.\n\n### Solution\nUpdate to TYPO3 versions 9.5.42 ELTS, 10.4.39 ELTS, 11.5.30 that fix the problem described above.\n\n### Credits\nThanks to Sybille Peters who reported this issue, and to TYPO3 core & security team member Oliver Hader who fixed the issue.\n\n### References\n* [TYPO3-CORE-SA-2023-004](https://typo3.org/security/advisory/typo3-core-sa-2023-004)\n* https://github.com/w8tcha/CKEditor-WordCount-Plugin/security/advisories/GHSA-q9w4-w667-qqj4","modified":"2026-01-30T00:52:30.005598Z","published":"2023-07-25T19:11:43Z","related":["CVE-2023-37905"],"database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-79"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2023-07-25T19:11:43Z"},"references":[{"type":"WEB","url":"https://github.com/TYPO3/typo3/security/advisories/GHSA-m8fw-p3cr-6jqc"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"},{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-core-sa-2023-004"}],"affected":[{"package":{"name":"typo3/cms-rte-ckeditor","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-rte-ckeditor"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.5.0"},{"fixed":"9.5.42"}]}],"versions":["v9.5.0","v9.5.1","v9.5.10","v9.5.11","v9.5.12","v9.5.13","v9.5.14","v9.5.15","v9.5.16","v9.5.17","v9.5.18","v9.5.19","v9.5.2","v9.5.20","v9.5.21","v9.5.22","v9.5.23","v9.5.24","v9.5.25","v9.5.26","v9.5.27","v9.5.28","v9.5.29","v9.5.3","v9.5.30","v9.5.31","v9.5.4","v9.5.5","v9.5.6","v9.5.7","v9.5.8","v9.5.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/07/GHSA-m8fw-p3cr-6jqc/GHSA-m8fw-p3cr-6jqc.json"}},{"package":{"name":"typo3/cms-rte-ckeditor","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-rte-ckeditor"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"10.0.0"},{"fixed":"10.4.39"}]}],"versions":["v10.0.0","v10.1.0","v10.2.0","v10.2.1","v10.2.2","v10.3.0","v10.4.0","v10.4.1","v10.4.10","v10.4.11","v10.4.12","v10.4.13","v10.4.14","v10.4.15","v10.4.16","v10.4.17","v10.4.18","v10.4.19","v10.4.2","v10.4.20","v10.4.21","v10.4.22","v10.4.23","v10.4.24","v10.4.25","v10.4.26","v10.4.27","v10.4.28","v10.4.29","v10.4.3","v10.4.30","v10.4.31","v10.4.32","v10.4.33","v10.4.34","v10.4.36","v10.4.37","v10.4.4","v10.4.5","v10.4.6","v10.4.7","v10.4.8","v10.4.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/07/GHSA-m8fw-p3cr-6jqc/GHSA-m8fw-p3cr-6jqc.json"}},{"package":{"name":"typo3/cms-rte-ckeditor","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-rte-ckeditor"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"11.0.0"},{"fixed":"11.5.30"}]}],"versions":["v11.0.0","v11.1.0","v11.1.1","v11.2.0","v11.3.0","v11.3.1","v11.3.2","v11.3.3","v11.4.0","v11.5.0","v11.5.1","v11.5.10","v11.5.11","v11.5.12","v11.5.13","v11.5.14","v11.5.15","v11.5.16","v11.5.17","v11.5.18","v11.5.19","v11.5.2","v11.5.20","v11.5.21","v11.5.22","v11.5.23","v11.5.24","v11.5.25","v11.5.26","v11.5.27","v11.5.28","v11.5.29","v11.5.3","v11.5.4","v11.5.5","v11.5.6","v11.5.7","v11.5.8","v11.5.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/07/GHSA-m8fw-p3cr-6jqc/GHSA-m8fw-p3cr-6jqc.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
