SCA: security update for @isaacs/brace-expansion (GHSA-7h2j-956f-4vf2)

critical Tenable Self-Hosted Container Security Plugin ID 437490

Description

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

 - @isaacs/brace-expansion is a hybrid CJS/ESM TypeScript fork of brace-expansion. Prior to version 5.0.1,
 @isaacs/brace-expansion is vulnerable to a denial of service (DoS) issue caused by unbounded brace range
 expansion. When an attacker provides a pattern containing repeated numeric brace ranges, the library
 attempts to eagerly generate every possible combination synchronously. Because the expansion grows
 exponentially, even a small input can consume excessive CPU and memory and may crash the Node.js process.
 This issue has been patched in version 5.0.1. (CVE-2026-25547)
