kafka-python prior to 2.3.2 contains a denial-of-service vulnerability in SCRAM authentication handling that allows a malicious or machine-in-the-middle broker to freeze the client event loop by supplying an excessively large iteration count. In scram.py, ScramClient.processserverfirstmessage...

CVE-2026-10143 kafka-python prior to 2.3.2 DoS via SCRAM Iteration Count in scram.py

kafka-python prior to 2.3.2 contains a denial-of-service vulnerability in SCRAM authentication handling that allows a malicious or machine-in-the-middle broker to freeze the client event loop by supplying an excessively large iteration count. In scram.py, ScramClient.processserverfirstmessage...

CVE-2026-10143

CVE-2026-10143 affects kafka-python prior to 2.3.2. The denial‑of‑service arises from ScramClient.process_server_first_message() passing the broker‑provided SCRAM iteration count directly to hashlib.pbkdf2_hmac() without validation in scram.py. This can freeze the client event loop, blocking prod...
