CVE-2026-10142: Dpkp Kafka-Python

High severity, CVSS 7.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Dpkp Kafka-Python: before 2.3.2 (fixed in 2.3.2)
