Node-wide denial of service via unbounded body read
Published Jul 11, 2022 · Updated Apr 22, 2025
Uncontrolled resource consumption in KubeEdge ServiceBus before 1.9.4, 1.10.0 through 1.10.1, and 1.11.0 allows local users to exhaust node memory. The ServiceBus basic HTTP handler passes the request body to io.ReadAll without a size limit, allowing allocation to grow with attacker-controlled input. Reachability requires an application on the edge host that can send HTTP requests to localhost and an explicitly enabled ServiceBus module; exhaustion prevents other containers and services from allocating memory.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=>= 1.10.0, < 1.10.2
- Affected versionversion== 1.11.0
- Affected versionversion=< 1.9.4
