CVE-2026-63767 Jul 20, 19:13 CRITICAL POC PATCH Act Now

Remote code execution in ktransformers (kvcache-ai) through version 0.6.3 allows unauthenticated attackers to run arbitrary shell commands by sending crafted pickle payloads to the SchedulerServer's ZMQ ROUTER socket, which is bound to all network interfaces (0.0.0.0). The flaw stems from unsafe pickle deserialization of RPC messages, letting an attacker weaponize a malicious __reduce__ method to execute code as the server process. Publicly available exploit code exists and VulnCheck published an advisory; there is no public exploit identified in CISA KEV, so this is not yet confirmed as actively exploited.

CVE-2026-26210 Apr 23, 21:24 CRITICAL POC PATCH Act Now

Remote code execution in KTransformers through 0.5.3 lets unauthenticated network attackers run arbitrary code by sending a crafted pickle payload to the scheduler RPC service used in balance_serve backend mode. The affected code binds a ZMQ ROUTER socket to all interfaces (0.0.0.0) with no authentication and passes received frames straight into pickle.loads(), so any host that can reach the scheduler port gains code execution as the ktransformers process. Publicly available exploit code exists (VulnCheck/chocapikk write-up) and a vendor upstream fix is available, though the EPSS probability is currently low at 0.04%.
