CVE-2026-10143

A flaw was found in kafka-python. A malicious or machine-in-the-middle broker could exploit a denial-of-service vulnerability during SCRAM authentication. By providing an excessively large iteration count, the broker can cause the client's event loop to freeze. This prevents critical operations such as sending messages, polling for new messages, and maintaining heartbeats, ultimately leading to consumer group eviction and persistent connection failures.
