Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Test your applicationsUpgrade vm2
to version 3.9.18 or higher.
vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules.
Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') via the inspect
method of vm.js
, which allows write
permissions.
Exploiting this vulnerability allows an attacker to edit options for the console.log
command.
Users unable to upgrade may make the inspect
method readonly
with vm.readonly(inspect)
after creating a VM.
