Deprecation: #95077 - FileDump CheckFileAccess hook

See forge#95077


The TYPO3 hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['FileDumpEID.php']['checkFileAccess'] which is executed in the \TYPO3\CMS\Core\Controller\FileDumpController class, enabling third-party code to perform additional access / security checks before dumping the requested file, has been marked as deprecated.

The accompanied PHP interface for the hook TYPO3\CMS\Core\Resource\Hook\FileDumpEIDHookInterface has been marked as deprecated as well.


If a hook is registered in a TYPO3 installation, a PHP E_USER_DEPRECATED error is triggered. The extension scanner also detects any usage of the deprecated interface as strong, and the definition of the hook as weak match.

Affected Installations

TYPO3 installations with custom extensions using this hook.


Migrate to the newly introduced \TYPO3\CMS\Core\Resource\Event\ModifyFileDumpEvent PSR-14 event.
