Details

Sandbox Breakout in realms-shim Versions of `realms-shim` prior to 1.2.0 are vulnerable to a Sandbox Breakout. `Reflect.construct` can be used on the sandboxed Function constructor to reach the prototypes of the primal Realm, which may allow an attacker to escape the sandbox and execute arbitrary code. ## Recommendation Upgrade to version 1.2.0 or later.
