Researchers Discover Critical Remote Code Execution Flaw in vm2 Sandbox Library

Posted by in category: security

The maintainers of the vm2 JavaScript sandbox module have shipped a patch to address a critical flaw that could be abused to break out of security boundaries and execute arbitrary shellcode.

The flaw, which affects all versions, including and prior to 3.9.14, was reported by researchers from South Korea-based KAIST WSP Lab on April 6, 2023, prompting vm2 to release a fix with version 3.9.15 on Friday.

“A threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox,” vm2 disclosed in an advisory.
