PHP Improper Input Validation Vulnerability - CVE-2020-7071
In PHP versions 7.3.x below 7.3.26 7.4.x below 7.4.14 and 8.0.0 when validating URL with functions like filter_var(url FILTER_VALIDATE_URL) PHP will accept an URL with invalid password as valid URL. This may lead to functions that rely on URL being valid to mis-parse the URL and produce wrong data as components of the URL.
