Name of the Vulnerable Software and Affected Versions TYPO3 FileSpool Extension (affected versions not specified)

Description The FileSpool extension for TYPO3 contains a flaw related to Insecure Deserialization. The extension’s code, derived from the TYPO3 core, reintroduces a previously addressed issue, even when the core TYPO3 system is updated.
