Important: #102800 - File Abstraction Layer enforces absolute paths to match project root or lockRootPath

See forge#102800


The File Abstraction Layer Local Driver has been adapted to verify whether a given absolute file path is allowed in order to prevent access to files outside the project root or to the additional root path restrictions defined in $GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath'].

$GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath'] = '/var/extra-storage';

// After
$GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath'] =  [
