SCA: security update for brace-expansion (GHSA-mh99-v99m-4gvg)

high Tenable Cloud Security Plugin ID 445572

Description

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

 - brace-expansion through 5.0.7 is vulnerable to denial of service via memory exhaustion. The expand()
 function limits the number of results with a max option (default 100,000) but does not bound the length of
 each result string. By chaining multiple brace groups, an attacker keeps the result count under the limit
 while making each result progressively longer, so total memory scales with both count and string length
 until the process hits a fatal, uncatchable out-of-memory error. About 7.5 KB of input
 ('{a,b}'.repeat(1500)) crashes a default Node.js process. Any application that passes attacker-influenced
 strings to brace-expansion.expand() - directly or transitively via minimatch / glob brace patterns - can
 be crashed by a small request. Fixed in 5.0.8 by adding a maxLength option (default 4,000,000) that bounds
 accumulated output and intermediate arrays. (CVE-2026-14257)

Solution

Update the brace-expansion library and its related packages to version 1.1.17 or later.
