Search: CVE-2026-14890

A pickle deserialization vulnerability (CVE-2026-14890) exists in the SGLang open-source framework's expert-parallel backup subsystem. This vulnerability allows unauthenticated remote code execution if the subsystem is enabled and reachable over the network. The issue arises because a ZeroMQ PULL socket binds to an external IP without authentication or deserialization safeguards, allowing malicious pickle payloads to be processed. No patch is currently available, and the maintainers have not responded to coordination efforts. Mitigations include disabling the pickle IPC feature and restricting network access to the vulnerable interface.
