Doc Text:	A flaw was found in PHP. An early return in the filter_var (FILTER_VALIDATE_URL) function results in invalid user information (username + password part of URLs) being treated as valid user information. This issue impacts users who expect only completely valid URLs to be returned by filter_var (FILTER_VALIDATE_URL). As this function is used to validate user-supplied strings, this issue exposes raw user input often.	Story Points:	---

Description Avinash Hanwate 2024-06-11 04:51:05 UTC

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.
