CWE: CWE-22 \u2014 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

Code:
	protected function isMounted($strFolder)
	{
		if (!$strFolder)
		{
			return false;
		}

		if (empty($this->arrFilemounts))
		{
			return true;
		}

		$path = $strFolder;

		while (\is_array($this->arrFilemounts) && substr_count($path, '/') > 0)
		{
			if (\in_array($path, $this->arrFilemounts))
			{
				return true;
			}

			$path = \dirname($path);
		}

		return false;
	}
