GHSA-2GG9-6P7W-6CPJ 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...

PT-2026-30274

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...

The vulnerability of the SandboxJS library, related to improper code generation management, allows a violator to escape from the isolated programming environment.

The vulnerability of the SandboxJS library is related to improper handling of code generation. Exploiting this vulnerability can allow a remote attacker to escape from an isolated programming environment...

CVE-2026-32723

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.35, SandboxJS timers have an execution-quota bypass. A global tick state currentTicks.current is shared between sandboxes. Timer string handlers are compiled at execution time using that global tick state rather than the scheduling...

CVE-2026-26954

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.34, it is possible to obtain arrays containing Function, which allows escaping the sandbox. Given an array containing Function, and Object.fromEntries, it is possible to construct p: Function where p is any constructible property. This...

Arbitrary Code Injection

SandboxJS is vulnerable to Arbitrary Code Injection. The vulnerability is due to improper isolation allowing access to Function via arrays and object construction, which allows an attacker to escape the sandbox and execute arbitrary code...

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...
