    🚨High - braces DoS via Recursive AST Walker Stack Overflow (CVE-2026-93687) braces <= 3.0.3 recursively walks nested brace AST nodes without enforcing a max recursion depth. A crafted deeply nested brace pattern (within input limits) triggers call stack exhaustion and an uncaught RangeError, terminating the Node.js process (DoS). 👉Affected: braces <= 3.0.3
