Joomla : Security Vulnerabilities, CVEs, (Directory traversal) CVSS score >= 9

The PharStreamWrapper (aka phar-stream-wrapper) package 2.x before 2.1.1 and 3.x before 3.1.1 for TYPO3 does not prevent directory traversal, which allows attackers to bypass a deserialization protection mechanism, as demonstrated by a phar:///path/bad.phar/../good.phar URL.

An issue was discovered in Joomla! before 3.9.5. The Media Manager component does not properly sanitize the folder parameter, allowing attackers to act outside the media manager root directory.

Directory traversal vulnerability in the Image Browser (com_imagebrowser) 0.1.5 component for Joomla! allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the folder parameter to index.php.
