Breaking: #98304 - Removed hook for modifying edit form user access

See forge#98304


The hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/alt_doc.php']['makeEditForm_accessCheck'] has been removed in favor of a new PSR-14 event \TYPO3\CMS\Backend\Form\Event\ModifyEditFormUserAccessEvent.

Additionally, the corresponding TYPO3\CMS\Backend\Form\Exception\AccessDeniedHookException, which had been thrown in case a hook denied the user access has been replaced by the TYPO3\CMS\Backend\Form\Exception\AccessDeniedListenerException.


Any hook implementation registered is not executed anymore in TYPO3 v12.0+. The AccessDeniedHookException is not thrown anymore. The extension scanner will report possible usages.

Affected Installations

All TYPO3 installations using this hook or the exception in custom extension code.


The hook is removed without deprecation in order to allow extensions to work with TYPO3 v11 (using the hook) and v12+ (using the new event).

Use the PSR-14 event as an improved replacement, providing an object-oriented approach as well as built-in convenience features and an increased amount of context information.

Any usage of the AccessDeniedHookException should be replaced by the AccessDeniedListenerException.
