It has been discovered that several AJAX routes used for the backend localization wizard failed to perform authorization checks. This allowed authenticated, low-privileged backend users to access information about records and content elements that fall outside of their permitted range. Exploiting this vulnerability requires a low-privileged backend user account. This issue affects TYPO3 CMS versions 10.0.0-10.4.59, 11.0.0-11.5.53, 12.0.0-12.4.48, 13.0.0-13.4.34 and 14.0.0-14.3.6.
