Host command execution via native Object constructor
Published Feb 25, 2026 · Updated Feb 25, 2026
Sandbox escape in AgentFront Enclave before 2.11.1 allows remote attackers to execute arbitrary commands on the host through untrusted code. The core sandbox exposes the native Object constructor, enabling property-descriptor access to a host memory-tracking callback or console inspect function and then the host Function constructor. Exploitation requires code execution inside an Enclave instance; the default memory limit exposes host_memory_track, while disabling it leaves the console-based path.

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.
