CVE-2026-22686 is a critical sandbox escape vulnerability affecting enclave-vm in agentfront enclave versions prior to 2.7.0. It allows untrusted JavaScript code within the sandbox to execute arbitrary code on the host Node.js runtime. This vulnerability has a CVSS score of 10.0 (Critical) due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. Attackers can trigger a host error, then traverse the prototype chain of the exposed Error object to access the host Function constructor, enabling arbitrary code execution. While there is no evidence of active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered significant community discussion with 11 mentions.
