Typo3

The extension extends TYPO3’ FileSpool component, which was vulnerable to Insecure Deserialization prior to TYPO3-CORE-SA-2026-004 https://typo3.org/security/advisory/typo3-core-sa-2026-004 .

Arbitrary PHP code execution in TYPO3 CMS versions 10.0.0 through 14.0.1 through unsafe deserialization of mail spool files, allowing local attackers with write access to the spool directory to execute malicious code when the mailer:spool:send command is executed. Affected versions span multiple release lines including 10.x, 11.x, 12.x, 13.x, and 14.x, requiring immediate patching to prevent web server compromise.

Backend users who had access to the recycler module could delete arbitrary data from any database table defined in the TCA - regardless of whether they had permission to that particular table. [CVSS 8.1 HIGH]

Backend users with access to the redirects module and write permission on the sys_redirect table were able to read, create, and modify any redirect record without restriction to the user’s own file-mounts or web-mounts. [CVSS 6.4 MEDIUM]

By exploiting the defVals parameter, attackers could bypass field‑level access checks during record creation in the TYPO3 backend. [CVSS 6.5 MEDIUM]
