CVE-2026-34217

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.36, a scope modification vulnerability exists in @nyariv/sandboxjs. The vulnerability allows untrusted sandboxed code to leak internal interpreter objects through the new operator, exposing sandbox scope objects in the scope hierarchy to...

CVE-2026-34208

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...

CVE-2026-34211 SandboxJS: Stack overflow DoS via deeply nested expressions in recursive descent parser

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.36, the @nyariv/sandboxjs parser contains unbounded recursion in the restOfExp function and the lispify/lispifyExpr call chain. An attacker can crash any Node.js process that parses untrusted input by supplying deeply nested expressions...

CVE-2026-34211

The CVE-2026-34211 entry describes an unbounded recursive vulnerability in @nyariv/sandboxjs (restOfExp and lispify/lispifyExpr) that can crash Node.js processes via deeply nested expressions. Connected sources (Rh/CVE-2026-34211, NVD, GHSA advisory) confirm the root cause is uncontrolled recursi...

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...

CVE-2026-34208

CVE-2026-34208 (SandboxJS) affects SandboxJS versions prior to 0.8.36. The vulnerability arises because an exposed constructor path (this.constructor.call(target, attackerObject)) can bypass the global-write protection and cause host global objects to be mutated by attacker-controlled payloads. T...
