composer is vulnerable to Arbitrary Code Execution. The vulnerability due to improper santization when parsing the installed.php/InstalledVersions.ph
file during the invocation of Composer. If Composer is invoked within a directory where InstalledVersions.ph
was tampered with by an attacker, arbitrary code execution can occur which may lead to local privilege escalation.
