How severe is CVE-2026-24118?

CVE-2026-24118 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which products are affected by CVE-2026-24118?

Affected package information for CVE-2026-24118 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2026-24118?

Apply the vm2_project vm2 security patch or hotfix for CVE-2026-24118 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2026-24118 across my infrastructure?

Inventory every vm2_project vm2 deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2026-24118 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2026-24118?

O3 detects and blocks CVE-2026-24118 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2026-24118 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-24118 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-24118?

CVE-2026-24118 has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 55th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-24118?

CVE-2026-24118 is classified as Code Injection (CWE-94), CWE-693 (CWE-693). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2026-24118?

CVE-2026-24118 affects vm2_project vm2. Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2026-24118 published, and has it been updated?

CVE-2026-24118 was published on May 4, 2026 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.0, VM2 suffers from a sandbox breakout vulnerability. This allows attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. This issue has been patched in version 3.11.0.
