CVE-2026-92951: Use of Incorrectly-Resolved Name or Reference in patriksimek vm2
vm2 before 3.11.7 contains an incorrect authorization vulnerability in the external package allowlist check that uses non-exact substring matching instead of full package-name boundary validation. Attackers can bypass the allowlist by requiring a colliding package name that contains an allowlisted package substring, causing vm2 to load and execute unauthorized host packages in the host context.
AI Analysis
Technical Summary
The vulnerability in vm2 versions prior to 3.11.7 involves an incorrect authorization mechanism in the external package allowlist check. Instead of validating package names with exact boundary matching, the allowlist check uses substring matching. Attackers can exploit this by crafting package names that include an allowlisted package substring, thereby bypassing the allowlist and causing vm2 to load and execute unauthorized host packages. This results in a critical security risk due to unauthorized code execution in the host environment.
Potential Impact
Successful exploitation allows attackers to bypass the package allowlist and execute unauthorized code in the host context, potentially leading to full compromise of the host environment. The CVSS 4.0 score of 9.4 reflects the critical nature of this vulnerability with high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
A fix is available in vm2 version 3.11.7. Users should upgrade to version 3.11.7 or later to remediate this vulnerability. No alternative mitigations or temporary fixes are indicated in the provided data.
