We have recently updated the TYPO3 core software of the websites we host for some of our customers from TYPO3 CMS 9.5.14 to TYPO3 CMS 9.5.18 and from TYPO3 CMS 10.4.1 to TYPO3 CMS 10.4.3 . These versions are maintenance releases and contain bug fixes only which repair some side effects from the previous security release update. You can read more about these updates at https://typo3.org/article/typo3-1042-and-9517-security-releases-published . Older versions of TYPO3 are no longer supported and will not receive security updates or bug fixes. Customers who are still using TYPO3 CMS 4.5, TYPO3 CMS 4.7 or TYPO3 CMS 6.2 versions are especially encouraged to upgrade to the latest version of TYPO3 CMS 6.2 (LTS) as soon as possible, and then to the latest version of TYPO3 CMS 7 (LTS) and then onto TYPO3 CMS 8 (LTS). If you want to upgrade your TYPO3 website to the latest version or add new features, please contact us .
