{"id":"CVE-2026-92940","summary":"vm2 3.11.3 through 3.11.6 HTTPS Credential Exposure via globalAgent","details":"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.","aliases":["GHSA-h85j-hv3c-qfgq"],"modified":"2026-09-18T03:48:42.903135206Z","published":"2026-09-17T13:46:04.218Z","database_specific":{"cwe_ids":["CWE-668"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92940.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92940.json"},{"type":"ADVISORY","url":"https://github.com/patriksimek/vm2/security/advisories/GHSA-h85j-hv3c-qfgq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92940"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vm2-3.11.3-through-3.11.6-https-credential-exposure-via-globalagent"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/patriksimek/vm2","events":[{"introduced":"093494c0c3ef2390d2e56909f9d56e290e6f18b0"},{"fixed":"0c5b63a228c0af88d4a0d364ab0b90df278d710e"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"3.11.3"},{"fixed":"3.11.7"}]}}],"versions":["3.11.6","v3.11.5","v3.11.4","v3.11.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92940.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
