CVE-2026-92941: Incorrect Permission Assignment for Critical Resource in patriksimek vm2
vm2 versions from 3.11.3 before 3.11.7 expose the host tls module to NodeVM sandbox code, allowing attackers to call tls.setDefaultCACertificates() and replace process-wide certificate authorities. Attackers with access to allowed tls and url builtins can use URLSearchParams to create host-realm arrays and manipulate the TLS trust store, enabling subsequent host HTTPS clients to accept attacker-controlled certificates.
AI Analysis
Technical Summary
CVE-2026-92941 affects patriksimek vm2 versions >=3.11.3 and <3.11.7 by exposing the host TLS module to NodeVM sandbox code. Attackers with access to the allowed tls and url builtins can invoke tls.setDefaultCACertificates() to replace the global certificate authorities. They can also use URLSearchParams to create host-realm arrays and manipulate the TLS trust store, causing subsequent HTTPS clients on the host to accept certificates controlled by the attacker.
Potential Impact
This vulnerability allows untrusted sandboxed code to alter the host's TLS trust store, undermining the security of HTTPS connections by making the host accept attacker-controlled certificates. This can lead to man-in-the-middle attacks or interception of secure communications by malicious actors.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
