Name of the Vulnerable Software and Affected Versions vm2 versions prior to 3.11.3

Description A sandbox breakout allows attackers to execute arbitrary commands on the host system. This occurs because a host exception can be caught using the yield* expression within an async generator. When the generator is closed via the return function, the value is awaited, and exceptions thrown in the then call are caught by the runtime and passed to the yield* iterator as the next value.

Recommendations Update to version 3.11.3.
