Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

vm2 is a sandbox that can run untrusted code with Node's built-in modules. In versions 3.9.17 and lower of vm2 it was possible to get a read-write reference to the node inspect method and edit options for console.log. As a result a threat actor can edit options for the console.log command. This vulnerability was patched in the release of version 3.9.18 of vm2. Users are advised to upgrade. Users unable …

Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

vm2 is a sandbox that can run untrusted code with Node's built-in modules. A sandbox escape vulnerability exists in vm2 for versions up to and including 3.9.17. It abuses an unexpected creation of a host object based on the specification of Proxy. As a result a threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox. This vulnerability was patched in …

Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

vm2 is a sandbox that can run untrusted code with allow listed Node's built-in modules. There exists a vulnerability in exception sanitization of vm2 for versions up to 3.9.16, allowing attackers to raise an unsanitized host exception inside handleException() which can be used to escape the sandbox and run arbitrary code in host context. This vulnerability was patched in the release of version 3.9.17 of vm2. There are no known …

Improper Control of Dynamically-Managed Code Resources

vm2 is a sandbox that can run untrusted code with allow listed Node's built-in modules. Prior to version 3.9.15, vm2 was not properly handling host objects passed to Error.prepareStackTrace in case of unhandled async errors. A threat actor could bypass the sandbox protections to gain remote code execution rights on the host running the sandbox. This vulnerability was patched in the release of version 3.9.15 of vm2. There are no …

Improper Control of Dynamically-Managed Code Resources

vm2 is a sandbox that can run untrusted code with allow listed Node's built-in modules. In versions prior to version 3.9.11, a threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox. This vulnerability was patched in the release of version 3.9.11 of vm2. There are no known workarounds.

Uncontrolled Recursion

This affects the package vm2 before 3.6.11. It is possible to trigger a RangeError exception from the host rather than the "sandboxed" context by reaching the stack call limit with an infinite recursion. The returned object is then used to reference the mainModule property of the host code running the script allowing it to spawn a child_process and execute arbitrary code.
