Summary

CVE-2026-92950 is a critical-severity Insecure Default Variable Initialization (CWE-453) vulnerability. Its CVSS base score is 9.3 (Critical).

Operationally, ranked at the 13th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to CM-2 (Baseline Configuration) and CM-6 (Configuration Settings) — see the control section below for these in your framework.

Vulnerability Data

vm2 before 3.11.7 contains a sandbox escape vulnerability in the CLI tool that allows attackers to execute arbitrary code in the host Node.js process. Attackers can supply a malicious script file to the vm2 CLI that uses require(__filename) to re-execute…

Mitigating Controls (NIST 800-53 r5) AI

Requires maintaining a documented baseline configuration that can enforce secure initial values instead of insecure defaults.

Requires establishing the most restrictive configuration settings, which directly overrides or prevents use of insecure default variable initializations.

Mandates application of security engineering principles during development that include use of secure defaults and proper variable initialization.

PR.PS-01 partial match
prevents

Hardened baselines and configuration management directly replace insecure product defaults with secure values.

PR.PS-06 partial match
prevents

Secure software development practices explicitly include choosing safe initial values instead of insecure defaults.

prevents

Secure development life cycle requires explicit secure initialization of variables.

prevents

Secure architecture principles include avoiding insecure defaults in design.

prevents

Secure coding standards mandate explicit, safe variable initialization.

finds

Security testing can detect insecure defaults but does not prevent them.

prevents

Configuration management enforces secure default values and prevents insecure initialization.
