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 3.11.7 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 Incorrect Resource Transfer Between Spheres incomplete filtering of Node.js registered internal symbols across the sandbox boundary. An attacker can corrupt host-visible stream state by obtaining real host symbols via Object.getOwnPropertySymbols on streamWeb.ReadableStream.prototype and using them as write keys on host stream objects, potentially bypassing host logic that relies on stream-state helpers.
