Security: ke_search indexer hook

[hmccloy]

There seems to be a problem with the ke_search indexer hook: Working with cascading fe_user groups, the permission check fails in modifyFileIndexEntryFromContentIndexer() and removes all groups, when the page or the content element is restricted to another usergroup than the storage is. As a result, the secure files are listed in the search result.

Code:
Line 81:
if ($feGroups) { $feGroups = implode( ',', GeneralUtility::keepItemsInArray(explode(',', $resourcePermissions), $feGroups) ); } else { $feGroups = $resourcePermissions; }
