How broadly exploitable is this vulnerability?

Any scenario where an attacker can submit or influence code that runs inside Enclave's sandbox may be affected. If that code can trigger tool failures or otherwise receive host-originated errors, the vulnerability can often be exploited to escape the sandbox and execute arbitrary host-level JavaScript.

Does exploitation require privileged or authenticated access?

Exploitation requires the ability to run code in the sandbox, which may or may not require authentication depending on the application. In multi-tenant or user-generated code environments, even low-privilege or untrusted users could potentially exploit the issue if they control sandboxed code.

What is the safest general fix pattern for this kind of issue?

The most robust pattern is to strictly separate realms by marshalling all host-to-sandbox values through a controlled serialization or deep-cloning layer, ensuring no host realm prototype chains or constructors cross the boundary. Error objects and other native types should be converted to plain, data-only structures before being exposed to sandboxed code.
