Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
GHSA-x6m4-chr9-cg97 affects the npm package vm2 in versions 3.11.0 up to but not including 3.11.7. Code running inside the sandbox under the default VM or NodeVM configuration can trigger a host-side syntax error and read its stack, which exposes absolute filesystem paths from vm2, Node.js internals, and the embedding application; the source describes this as information disclosure only, with no code execution. Upgrade vm2 to version 3.11.7, which is the fixed version listed.
