CVE-2026-25533Public exploit

Host command execution via leaked error prototypes

Published Feb 6, 2026 · Updated Feb 6, 2026

Sandbox escape in AgentFront Enclave before 2.10.1 allows local users to execute arbitrary commands on the host through untrusted JavaScript. Infinite recursion in Node.js vm yields a host-realm error object, and computed prototype access reaches the host Function constructor despite AST filtering. Execution requires the ability to submit code to an Enclave instance and grants that code the host process's filesystem, environment, and command privileges.
