CVE-2026-77465: toml-node: Uncontrolled Recursion

toml.parse() crashes with an uncaught RangeError: Maximum call stack size exceeded when parsing deeply nested arrays or inline tables. The parser is generated by Peggy 5.1.0 (a PEG parser generator) as a recursive-descent parser; the value rule mutually recurses with the array and inline-table rules with no depth limit, so nesting depth equal to the input depth exhausts Node’s call stack.

A small payload — a bare array nested a few thousand levels deep (~5–6 KB) — reliably crashes the process on a default Node.js configuration. toml has ~47 million monthly downloads.
