      <title>CVE-2026-34217 — SandboxJS has a Sandbox Escape via Prop Object Leak in New Handler</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-34217</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; nyariv SandboxJS&lt;/p&gt;
&lt;p&gt;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 untrusted code; an unexpected and undesired exploit. While this could allow modifying scopes inside the sandbox, code evaluation remains sandboxed and prototypes remain protected throughout the execution. This vulnerability is fixed in 0.8.36.&lt;/p&gt;</description>
