CVE-2026-34208 SandboxJS: Sandbox integrity escape

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.36, SandboxJS blocks direct assignment to global objects for example Math.random = ..., but this protection can be bypassed through an exposed callable constructor path: this.constructor.calltarget, attackerObject. Because this.constructo...
