CVE-2026-112268 · sglang-router through 0.3.2 Authorization Bypass via Mesh HA Management Routes
This page contains facts from public vulnerability sources. Check the original advisory before updating.
sglang-router (sgl-model-gateway) through 0.3.2 contains an authorization bypass vulnerability that allows holders of the data-plane API key to access mesh HA management routes because /ha/* endpoints skip control-plane Admin role checks. Attackers can read cluster topology, write gossiped configuration, change global rate limits, and call POST /ha/shutdown to silently dissolve HA coordination.
