TIMELINE May 12 Reserved by GitHub_M May 13 Published (CNA: GitHub_M) Aug 6 EXPLOIT PUBLISHED — CVE-2026-45411 (patriksimek vm2). Public exploit reference added.
vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.3, it is possible to catch a host exception using the yield* expression inside an async generator. When the generator is closed using the return function, the value is awaited on and exceptions thrown in the then call will be caught by the runtime and passed to the yield* iterator as the next value. This allows attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. This vulnerability is fixed in 3.11.3.
