In PHP versions 7.3.x below 7.3.29, 7.4.x below 7.4.21 and 8.0.x below 8.0.8, when using URL validation functionality via filter_var() function with FILTER_VALIDATE_URL parameter, an URL with invalid password field can be accepted as valid. This can lead to the code incorrectly parsing the URL and potentially leading to other security implications - like contacting a wrong server or making a wrong access decision.
A flaw was found in php. Currently, php's FILTER_VALIDATE_URL check doesn't recognize some non-compliant RFC 3986 URLs and returns them as valid. This flaw allows an attacker to craft URLs, which depending on how the URL filter checking is used on the application side, lead to Server Side Request Forgery. This issue presents an integrity risk for the application, as eventually, the attacker can manipulate resources that shouldn't be fully available for users.
