CriticalCVSS: 10.0Last Updated: May 14, 2026
vm2 - Prototype Pollution
Overview
vm2 3.9.6 to 3.10.5 contains a prototype pollution caused by exposing mutable proxies for host-realm intrinsic prototypes in the bridge, letting attacker-controlled JavaScript mutate shared Object, Array, and Function prototypes, exploit requires attacker-controlled code execution inside the sandbox.
Severity & Score
Impact
Attackers can modify shared host prototypes, leading to arbitrary code execution or sandbox escape.
Mitigation
Update to version 3.11.0 or later.

[1/5] Executive Summary – Key Threat‑Intelligence Highlights (13 May – 14 May 2026) Below is a concise, prioritized briefing of the most impactful security events that are directly relevant to our IoT‑focused subsidiary (Linux/Ubuntu workstations, Azure Container Apps, Kubernetes, and the typical development toolchain). Each bullet includes a full‑length source link as required. --- 1. Critical Vulnerabilities that Touch Our Stack : VM2 sandbox‑escape (CVE‑2026‑44005) – Remote code execution in the popular Node.js sandbox library used by many npm packages. • Our container images (Wolfi, Alpine, Debian, Ubuntu) often run Node‑based build tools and CI/CD scripts; a compromised VM2 could break isolation and lead to host compromise. • https://cveawg.mitre.org/api/cve/CVE-2026-44005 WebdriverIO CI/CD command‑injection (CVE‑2026‑25244) – Malicious Git branch names can trigger code execution on CI runners. • Directly affects our Azure Pipelines / GitHub Actions workflows that use WebdriverIO for UI testing. • https://mastodon.social/@netsecio/116567593278695651 Firefox high‑severity bugs discovered by Anthropic’s Mythos AI (CVE‑2026‑33824, CVE‑2026‑33827) – Remote‑code‑execution paths in the browser. • Developers and QA staff use Firefox on Ubuntu workstations; a compromised browser can be a foothold for credential theft. • https://www.cyberhub.blog/article/25855-anthropics-mythos-ai-discovers-multiple-high-severity-vulnerabilities-in-firefox Windows BitLocker zero‑day (public PoC) – Bypass of drive encryption on Windows 11. • Some engineering laptops still run Windows 11 with BitLocker; the flaw could expose source code or design data. • https://www.bleepingcomputer.com/news/security/windows-bitlocker-zero-day-gives-access-to-protected-drives-poc-released/ Microsoft Patch Tuesday (May 2026) – 120 CVEs fixed, 29 are critical RCE bugs affecting Windows, Azure services, and core libraries. • Our Azure Container Apps and any Windows‑based build agents must be patched immediately to stay protected. • https://securebulletin.com/microsoft-patch-tuesday-may-2026-120-vulnerabilities-fixed-including-29-critical-rce-flaws/ #infosecnews
