Remote Code Execution (RCE)

isolated-vm is an Access to multiple isolates

Affected versions of this package are vulnerable to Remote Code Execution (RCE) when untrusted v8 cached data is passed to the API through CachedDataOptions, by allowing attackers to bypass the sandbox and run arbitrary code in the nodejs process.

Note:

This issue has been addressed by improving the documentation.

״CachedData contains compiled machine code. That means you should not accept cachedData payloads from a user, otherwise they may be able to run arbitrary code.״

How to fix Remote Code Execution (RCE)?

Upgrade isolated-vm to version 4.3.7 or higher.

<4.3.7
