Last modified

CVE-2024-5458 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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.. EPSS estimates a 12.12% chance of exploitation in the next 30 days.
