CVE-2026-92933
Description
A flaw was found in vm2. The NodeVM component exposes the host util module, including the util.getCallSites() function, to the sandbox as an unfiltered copy. On Node.js versions 22.9 and later, this allows sandboxed code to access util.getCallSites(), which can return the host process's full call stack. This information disclosure includes sensitive details such as absolute file paths, function names, and line numbers, bypassing existing host-frame redaction mechanisms.
Statement
This Moderate severity flaw in vm2 allows a sandboxed Node.js environment to disclose sensitive host process information, including file paths and function names. This bypasses existing stack frame redaction, potentially exposing internal application details within Red Hat Ansible Automation Platform and Red Hat Developer Hub deployments where vm2 is used to execute untrusted code. The impact is limited to information disclosure, not arbitrary code execution.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
