CVE-2026-92948

Description

A flaw was found in vm2. This vulnerability allows an attacker with permission to run code inside the sandbox to escape containment and achieve arbitrary code execution on the host system. Due to improper validation of built-in module names, the sandbox fails to block access to sensitive host functions. An attacker can exploit this issue by supplying a specially crafted module identifier, allowing them to spawn an unrestricted process on the host.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
