CVE-2019-11831critical
Description
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.
