Description

This security bulletin contains information about 3 vulnerabilities.


1) Protection Mechanism Failure (CVE-ID: CVE-2026-26332)

CWE-ID: CWE-693 - Protection Mechanism Failure

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper sandbox enforcement in the SuppressedError handling in vm2 when processing crafted code inside the sandbox. A remote attacker can trigger a sandbox escape to execute arbitrary code.

This issue was observed in vm2 v3.10.4 on Node.js v24.13.0.


2) Protection Mechanism Failure (CVE-ID: CVE-2026-24781)

CWE-ID: CWE-693 - Protection Mechanism Failure

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary commands on the host system.

The vulnerability exists due to improper sandbox enforcement in the inspect function when unwrapping proxies during object inspection. A remote attacker can execute crafted code inside a vm2 sandbox to execute arbitrary commands on the host system.

Exploitation requires the ability to run arbitrary code within the context of a vm2 sandbox.


3) Improper access control (CVE-ID: CVE-2026-24118)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the host system.

The vulnerability exists due to improper access control in the vm2 sandbox boundary handling of the __lookupGetter__ method when executing untrusted code inside a vm2 sandbox. A remote attacker can invoke host-context methods through Buffer.apply and retrieve the host Function constructor to execute arbitrary code on the host system.

Exploitation requires the ability to run arbitrary code within the context of a vm2 sandbox.
