Descriptions

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.

En las versiones de PHP 8.1.* anteriores a 8.1.29, 8.2.* anteriores a 8.2.20, 8.3.* anteriores a 8.3.8, debido a un error de lógica de código, funciones de filtrado como filter_var al validar URL (FILTER_VALIDATE_URL) para ciertos tipos de URL la función dará como resultado que la información de usuario no válida (nombre de usuario + contraseña parte de las URL) se trate como información de usuario válida. Esto puede hacer que el código posterior acepte URL no válidas como válidas y las analice incorrectamente.
