Overview

What is CVE-2024-5458?

In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, due to a code logic error, filtering functions such as filter_var when validating URLs (FILTER_VALIDATE_URL) for certain types of URLs the function will result in invalid user information (username + password part of URLs) being treated as valid user information.

This may lead to the downstream code accepting invalid URLs as valid and parsing them incorrectly.
