CVE-2026-92947: Exposure of Sensitive Information to an Unauthorized Actor in patriksimek vm2
CVE-2026-92947 is a critical vulnerability in patriksimek vm2 versions before 3.11.7 that allows sandboxed code to access Node.js shared Buffer pool memory. This exposure enables unauthorized reading and writing of host memory buffers, potentially leaking sensitive data and causing denial-of-service conditions.
AI Analysis
Technical Summary
The vulnerability in patriksimek vm2 prior to version 3.11.7 involves exposure of Node.js's shared Buffer pool to sandboxed code. Specifically, sandboxed code can obtain ArrayBuffers from small allocations and thereby read and write host-realm buffers used by Buffer.from, Buffer.concat, and related Buffer allocations. This leads to disclosure of sensitive host memory and potential denial-of-service attacks due to memory corruption or exhaustion.
Potential Impact
Exploitation of this vulnerability allows untrusted sandboxed code to access and modify host memory buffers, resulting in sensitive information disclosure and possible denial-of-service conditions. The vulnerability has a CVSS 4.0 score of 10.0, indicating critical severity with high impact on confidentiality, integrity, and availability without requiring privileges or user interaction.
Mitigation Recommendations
A fix is available in patriksimek vm2 version 3.11.7. Users should upgrade to version 3.11.7 or later to remediate this vulnerability. No other mitigation guidance is provided, and upgrading is the recommended action.
