TYPO3 Core

Spaces or umlauts in the filename or path make a secure download link generated via the function filelink crash, i.e. the error message "Calculated juHash did not match the submitted juHash" is shown.

This is because the URL-encoding used for calculating the file hash differs in class.tslib_fe.php and class.tslib_content.php.
The verification routine for the download link in class.tslib_fe.php should use
str_replace('%2F', '/', rawurlencode($this->jumpurl))
instead of
$this->jumpurl
for calculating the hash - as it is done in the function filelink.

A patch is provided.
