Upgrade toml to version 5.0.1 or higher.
Overview
Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the compiler in lib/compiler.js, where processing an array-of-tables header causes a full rescan of every path defined so far. An attacker can supply a TOML document with a large number of array-of-tables headers to trigger quadratic time complexity, crashing the process.
