{"id":"GHSA-59jf-3q9v-rh6g","summary":"By-passing Cross-Site Scripting Protection in HTML Sanitizer","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\nDue to an encoding issue in the serialization layer, malicious markup nested in a `noscript` element was not encoded correctly. `noscript` is disabled in the default configuration, but might have been enabled in custom scenarios. This allows bypassing the cross-site scripting mechanism of [`typo3/html-sanitizer`](https://packagist.org/packages/typo3/html-sanitizer).\n\n### Solution\nUpdate to `typo3/html-sanitizer` versions 1.5.1 or 2.1.2 that fix the problem described.\n\n### Credits\nThanks to David Klein and Yaniv Nizry who reported this issue, and to TYPO3 security team members Oliver Hader and Benjamin Franzke who fixed the issue.\n\n### References\n* [TYPO3-CORE-SA-2023-002](https://typo3.org/security/advisory/typo3-core-sa-2023-002)\n","aliases":["CVE-2023-38500"],"modified":"2026-09-10T03:49:54.331507355Z","published":"2023-07-25T18:27:16Z","database_specific":{"cwe_ids":["CWE-79"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2023-07-25T18:27:16Z","nvd_published_at":"2023-07-25T21:15:11Z"},"references":[{"type":"WEB","url":"https://github.com/TYPO3/html-sanitizer/security/advisories/GHSA-59jf-3q9v-rh6g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-38500"},{"type":"WEB","url":"https://github.com/TYPO3/html-sanitizer/commit/e3026f589fef0be8c3574ee3f0a0bfbe33d7ebdb"},{"type":"PACKAGE","url":"https://github.com/TYPO3/html-sanitizer"},{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-core-sa-2023-002"}],"affected":[{"package":{"name":"typo3/html-sanitizer","ecosystem":"Packagist","purl":"pkg:composer/typo3/html-sanitizer"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.0"},{"fixed":"1.5.1"}]}],"versions":["v1.0.0","v1.0.1","v1.0.2","v1.0.3","v1.0.4","v1.0.5","v1.0.6","v1.0.7","v1.5.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/07/GHSA-59jf-3q9v-rh6g/GHSA-59jf-3q9v-rh6g.json"}},{"package":{"name":"typo3/html-sanitizer","ecosystem":"Packagist","purl":"pkg:composer/typo3/html-sanitizer"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0.0"},{"fixed":"2.1.2"}]}],"versions":["v2.0.0","v2.0.1","v2.0.10","v2.0.11","v2.0.12","v2.0.13","v2.0.14","v2.0.15","v2.0.16","v2.0.2","v2.0.3","v2.0.4","v2.0.5","v2.0.6","v2.0.7","v2.0.8","v2.0.9","v2.1.0","v2.1.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/07/GHSA-59jf-3q9v-rh6g/GHSA-59jf-3q9v-rh6g.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"}]}
