CVE-2026-120330 Details
Description
Backend actions and ajax routes of the mail module do not check whether the backend user has access to the page of the requested mail or recipient group. Backend users with access to the mail module can view, change, send and export mails and recipient groups outside their web mounts, including the personal data of recipients.
A broken access control vulnerability has been identified in the TYPO3 Mail extension, affecting versions 3.12.4 and below, as well as 4.0.0 to 4.1.0. The vulnerability arises because backend actions and AJAX routes in the mail module do not properly verify whether a backend user has access to the specific page of the requested mail or recipient group. As a result, backend users with access to the mail module can view, modify, send, and export mails and recipient groups beyond their designated web mounts. This includes access to personal data of recipients.
Users are advised to update to version 3.12.5 or 4.2.0, available through the TYPO3 extension manager, Packagist, or by downloading the ZIP files from the TYPO3 extensions website.
