RHSA-2026:54436 PUBLISHED CVSS 7.5 HIGH

A flaw was found in the brace-expansion library. The `expand()` function does not apply `maxLength` when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is due to an incomplete mitigation of CVE-2026-14257.
