Source: node-brace-expansion

Hi,

The following vulnerability was published for node-brace-expansion.

CVE-2026-33750[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
