SCA: security update for brace-expansion (GHSA-jxxr-4gwj-5jf2)

high Tenable Cloud Security Plugin ID 442049

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. From 5.0.0
 to before 5.0.6, the max option was being applied too late. When expanding a single large numeric range
 like {1..10000000}, the sequence generation loop generates all 10 million intermediate elements before the
 max limit is applied With max=10, the output is correctly limited to 10 items, but the process still
 allocates ~505 MB and spends ~800ms building the full intermediate array. This vulnerability is fixed in
 5.0.6. (CVE-2026-45149)

Solution

Update the brace-expansion library and its related packages to version 5.0.6 or later.
