php7 is vulnerable to privilege escalation. The vulnerability is possible due to insufficient validation of URL performed via the “FILTER_VALIDATE_URL” setting. A remote attacker can use the “@” characters in the URL to bypass implemented filter and force the application to accept arbitrary URL instead of the defined by the option.
