{"id":"CVE-2022-23500","aliases":["BIT-typo3-2022-23500","GHSA-8c28-5mp7-v24h"],"url":"https://o3.security/vulnerability/CVE-2022-23500","summary":"TYPO3 subject to Uncontrolled Recursion resulting in Denial of Service","details":"TYPO3 is an open source PHP based web content management system. In versions prior to 9.5.38, 10.4.33, 11.5.20, and 12.1.1, requesting invalid or non-existing resources via HTTP triggers the page error handler, which again could retrieve content to be shown as an error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack until the limits of the web server are exceeded. This vulnerability is very similar, but not identical, to the one described in CVE-2021-21359. This issue is patched in versions 9.5.38 ELTS, 10.4.33, 11.5.20 or 12.1.1.","published":"2022-12-14T07:07:05.039Z","modified":"2026-08-08T03:47:27.430422227Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"9.5.38"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"10.4.33"},{"ecosystem":"Packagist","name":"typo3/cms-core","fixedVersion":"11.5.20"},{"ecosystem":"Packagist","name":"typo3/cms","fixedVersion":"10.4.33"},{"ecosystem":"Packagist","name":"typo3/cms","fixedVersion":"11.5.20"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23500.json"},{"type":"ADVISORY","url":"https://github.com/TYPO3/typo3/security/advisories/GHSA-8c28-5mp7-v24h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23500"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:47:27.430422227Z"}}
