GHSA-HG73-4W7G-Q96W SandboxJS: Sandbox Escape via Prop Object Leak in New Handler

Description A scope modification vulnerability exists in @nyariv/sandboxjs version 0.8.35 and below. The vulnerability allows untrusted sandboxed code to leak internal interpreter objects through the new operator, exposing sandbox scope objects in the scope hierarchy to untrusted code; an...

Improperly Controlled Modification of Dynamically-Determined Object Attributes

Overview @nyariv/sandboxjs is a Javascript sandboxing library. Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes through the constructor process. An attacker can modify host global objects and persist these changes...

SandboxJS: Sandbox integrity escape

Summary 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.constructor resolves to the internal SandboxGlobal function and...
