RUSTSEC-2026-0179 Unbounded SCRAM iteration count allows a malicious server to cause CPU-exhaustion denial of service

A malicious, compromised, or man-in-the-middle server can supply an arbitrarily large SCRAM-SHA-256 PBKDF2 iteration count during authentication. The client runs it inline with no upper bound, pinning a tokio worker thread for minutes per connection, possibly stalling the whole async runtime...

SUSE CVE-2026-10143

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

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...

DEBIAN-CVE-2026-10143

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...
