SCA: security update for @nyariv/sandboxjs (GHSA-7x3h-rm86-3342)

critical Tenable Cloud Security Plugin ID 437583

Description

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

 - SandboxJS is a JavaScript sandboxing library. Prior to 0.8.29, there is a sandbox escape vulnerability due
 to a mismatch between the key on which the validation is performed and the key used for accessing
 properties. Even though the key used in property accesses is annotated as string, this is never enforced.
 So, attackers can pass malicious objects that coerce to different string values when used, e.g., one for
 the time the key is sanitized using hasOwnProperty(key) and a different one for when the key is used for
 the actual property access. This vulnerability is fixed in 0.8.29. (CVE-2026-25641)
