Description

In PHP versions 7.3.x below 7.3.26, 7.4.x below 7.4.14 and 8.0.0, when validating URL with functions like filter_var($url, FILTER_VALIDATE_URL), PHP will accept an URL with invalid password as valid URL. This may lead to functions that rely on URL being valid to mis-parse the URL and produce wrong data as components of the URL.

Affected products and versions

  • PHP — From 7.3.0 (including) to 7.3.26 (excluding)
  • PHP — From 7.4.0 (including) to 7.4.14 (excluding)
  • PHP — From 8.0.0 (including) to 8.0.1 (excluding)
