brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation

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...
