CVE-2026-92960 (GCVE-0-2026-92960)

Vulnerability from cvelistv5 – Published: 2026-09-17 13:46 – Updated: 2026-09-17 14:22

Title

vm2 before 3.11.6 Process-wide State Exposure via os and dns

Summary

vm2 before 3.11.6 fails to restrict access to os and dns builtins under the builtin: ['*'] configuration, allowing sandbox code to read host process identity and network topology. Attackers can invoke dns.setServers() to hijack the host process DNS resolver globally, redirecting all subsequent host DNS queries through an attacker-controlled resolver.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
