{"id":"CVE-2026-92940","published":"2026-09-17T14:17:59.143","lastModified":"2026-09-17T20:18:59.213","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.","cvssScore":10,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:L","cwes":["CWE-668"],"vendors":[],"products":[],"references":[{"url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-h85j-hv3c-qfgq","tags":[]},{"url":"https://www.vulncheck.com/advisories/vm2-3.11.3-through-3.11.6-https-credential-exposure-via-globalagent","tags":[]}],"exploitRefs":[{"url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-h85j-hv3c-qfgq","tags":[]}],"hasPoc":true,"ai":{"summary":"This flaw allows sandboxed code to access and manipulate host HTTPS requests, enabling credential theft and unauthorized request issuance.","exploitability":"Exploitation requires explicit NodeVM configuration to allow 'https' and access to the host's globalAgent.
