影響: npm:toml <= 5.0.0 → 5.0.1
toml.parse() is vulnerable to a quadratic-complexity (O(n²)) denial-of-service via a single long dotted key, table header, or inline-table key. A ~100KB crafted document causes a multi-second synchronous hang; a ~200KB document crashes the Node.js process outright with an uncatchable out-of-memory error. This is a separate, unpatched code path from the previously fixed stack-overflow DoS (GHSA-82x6-q7mm-w9cf) — it requires no array/inline-table nesting at all, and is confirmed unaffected by the…
