In 3.10.5, NodeVM's require.root path restriction can be bypassed using filesystem symlinks, allowing sandboxed code to load modules from outside the allowed root directory in host context. Because path validation uses path.resolve() (which does not dereference symlinks) but module loading uses Node's native require() (which does), an attacker can load arbitrary host-realm modules and achieve remote code execution. This vulnerability is fixed in 3.11.0.","state":0,"publishedAt":"2026-05-13T18:16:16.317+00:00","modifiedAt":"2026-09-07T13:19:53.37+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","score":8.5,"severity":"HIGH"},{"system":"CVSS 3.1 · 0b0ca135-0b70-47e7-9f44-1890c2a1c46c · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","score":8.5,"severity":"HIGH"}],"references":["https://github.com/patriksimek/vm2/security/advisories/GHSA-cp6g-6699-wx9c","https://access.redhat.com/errata/RHSA-2026:50850","https://access.redhat.com/security/cve/CVE-2026-43998","https://bugzilla.redhat.com/show_bug.cgi?id=2477206","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-43998.json"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-43998","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-59"],"productCriteria":["cpe:2.3:a:vm2_project:vm2:3.10.5:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-05-13T18:16:16.317","lastModified":"2026-09-07T13:19:53.370"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
