urllib3 is vulnerable to denial of service. The _encode_invalid_chars
function in util/url.py
allows an attacker to cause a denial of service condition through long processing time due to an inefficient algorithm when parsing invalid characters, potentially resulting in an application crash when system resources are depleted.
