urllib3 - CVE-2026-21441

urllib3 is vulnerable to a Denial-Of-Service (DoS). The vulnerability is due to unbounded decompression of redirect response bodies in the streaming API, where urllib3 decompresses entire redirect responses regardless of read limits, allowing a malicious server to trigger excessive resource consumption via decompression bombs when streaming content from untrusted sources.
