Hi, The following vulnerability was published for python-kafka. CVE-2026-10142[0]: | kafka-python prior to 2.3.2 contains a denial-of-service | vulnerability in the protocol parser that allows a malicious broker | or machine-in-the-middle attacker to exhaust memory or hang | connections by sending a crafted 4-byte frame length value without | bounds validation. Attackers can send a specially crafted frame | length through the receive_bytes() function to trigger either a | multi-gigabyte memory allocation or an uncaught ValueError that | leaves the connection in a broken state, causing requests to hang | and consumers to stop heartbeating until restart. https://github.com/dpkp/kafka-python/pull/3019 https://github.com/dpkp/kafka-python/pull/3026 Fixed by: https://github.com/dpkp/kafka-python/commit/6e4831444f972d169cdd11f5c8d50333cea3f19b (3.0.0) If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
