SCA: security update for brace-expansion (GHSA-f886-m6hf-6m8v)

high Tenable Self-Hosted Container Security Plugin ID 439261

Description

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

 - The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to
 versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13, a brace pattern with a zero step value (e.g., `{1..2..0}`)
 causes the sequence generation loop to run indefinitely, making the process hang for seconds and allocate
 heaps of memory. Versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13 fix the issue. As a workaround, sanitize strings
 passed to `expand()` to ensure a step value of `0` is not used. (CVE-2026-33750)

Solution

Update the brace-expansion library and its related packages to version 1.1.13 or later.
