SCA: security update for @nyariv/sandboxjs (GHSA-g8f2-4f4f-5jqw)

critical Tenable Self-Hosted Container Security Plugin ID 441750

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - SandboxJS is a JavaScript sandboxing library. Prior to 0.9.6, sandbox-defined functions expose
 Function.caller, allowing sandboxed code to recover the internal LispType.Call runtime callback. That
 callback can then be invoked with attacker-controlled fake context and obj values to extract blocked host
 statics, recover the real host Function constructor, and execute arbitrary host JavaScript. This
 vulnerability is fixed in 0.9.6. (CVE-2026-43898)

Solution

Update the @nyariv/sandboxjs library and its related packages to version 0.9.6 or later.
