CVE-2026-25533: Enclave has a sandbox escape via infinite recursion and error objects

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2026-02-06 · updated 2026-06-17
• Weakness: CWE-835

Description

Enclave is a secure JavaScript sandbox designed for safe AI agent code execution. Prior to 2.10.1, the existing layers of security in enclave-vm are insufficient: The AST sanitization can be bypassed with dynamic property accesses, the hardening of the error objects does not cover the peculiar behavior or the vm module and the function constructor access prevention can be side-stepped by leveraging host object references. This vulnerability is fixed in 2.10.1.

Affected products

• agentfront enclave: from 2.7.0 before 2.10.1 — fixed in 2.10.1

How to fix

Upgrade to a fixed version: agentfront enclave 2.10.1. Check the vendor advisory for mitigations.
