NVD Description
Note: Versions mentioned in the description apply only to the upstream php7-fileinfo package and not the php7-fileinfo package as distributed by SLES.
See How to fix? for SLES:15.3 relevant fixed versions and status.
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.
