GHSA-ggff-9mj3-7246
No affected components available
Description
The extension extends TYPO3’s FileSpool component, which was vulnerable to Insecure Deserialization prior to TYPO3-CORE-SA-2026-004. Since the related fix is overwritten by the extension, using the extension with a patched TYPO3 core version still allows for Insecure Deserialization, because the affected vulnerable code was extracted from TYPO3 core to the extension.
More information about this vulnerability can be found in the related TYPO3 Core Security Advisory TYPO3-CORE-SA-2026-004.
