CVE-2026-26954

SandboxJS is a JavaScript sandboxing library. Before version 0.8.34, it can leak arrays containing Function, enabling sandbox escape when used with Object.fromEntries to construct {[p]: Function} for any constructible property. This leads to Sandbox Escape with potential RCE as described in multi...
