CVE-2026-26210
Last modified
CVE-2026-26210 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. KTransformers through 0.5.3 contains an unsafe deserialization vulnerability in the balance_serve backend mode where the scheduler RPC server binds a ZMQ ROUTER socket to all interfaces with no authentication and deserializes incoming messages using pickle.loads() without validation. Attackers can send a crafted pickle payload to the exposed ZMQ socket to execute arbitrary code on the server with the privileges of the ktransformers process.. EPSS estimates a 0.70% chance of exploitation in the next 30 days.
