Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Versions 3.11.3 up to but not including 3.11.7 of the npm package vm2 are affected. When a NodeVM is allowed to require the https builtin, sandbox code can register listeners on the host process's shared https.globalAgent and receive host request options and the live TLS socket. An attacker who can submit code to such a sandbox can read host bearer tokens and plaintext responses on reused connections and perform authenticated actions. The source says the exposure happens only when the host uses the default HTTPS agent. Upgrade to vm2 3.11.7, which is the fixed version listed.
