Vulnerability	Vulnerable Version
H Uncontrolled Recursion Affected versions of this package are vulnerable to Uncontrolled Recursion in `lib/parser.js`, where the mutually recursive `peg$parsevalue()`, `peg$parsearray()`, and `peg$parseinline_table_entry()` functions recurse to the input's nesting depth with no depth limit. An attacker can crash the process with a `RangeError: Maximum call stack size exceeded` by supplying a deeply nested TOML document, such as a ~6 KB payload nested about 2,500 levels (`a=[[[...]]]`). This requires the application to call `toml.parse()` on untrusted input, and error handlers that catch only `SyntaxError` do not contain the resulting `RangeError`, which is not a `SyntaxError` subclass. How to fix Uncontrolled Recursion? A fix was pushed into the `master` branch but not yet published.	[0,)
H Prototype Pollution Affected versions of this package are vulnerable to Prototype Pollution in the `deepRef` function of `lib/compiler.js`, which traverses through a scalar value into the prototype chain, and whose containment guard is missed because `currentPath` inconsistently holds arrays that coerce to comma-separated strings (`"a,b"`) while the guard checks dot-separated paths (`"a.b"`). An attacker can inject arbitrary properties onto `Object.prototype`, affecting every object in the process, by supplying a TOML document whose table path steps through a scalar into `__proto__.__proto__`, for example `[a.b.y.__proto__.__proto__]` after `y = 1`. This requires the application to parse attacker-controlled TOML. How to fix Prototype Pollution? A fix was pushed into the `master` branch but not yet published.	[0,)

Uncontrolled Recursion

Affected versions of this package are vulnerable to Uncontrolled Recursion in lib/parser.js, where the mutually recursive peg$parsevalue(), peg$parsearray(), and peg$parseinline_table_entry() functions recurse to the input's nesting depth with no depth limit. An attacker can crash the process with a RangeError: Maximum call stack size exceeded by supplying a deeply nested TOML document, such as a ~6 KB payload nested about 2,500 levels (a=[[[...]]]). This requires the application to call toml.parse() on untrusted input, and error handlers that catch only SyntaxError do not contain the resulting RangeError, which is not a SyntaxError subclass.

Prototype Pollution

Affected versions of this package are vulnerable to Prototype Pollution in the deepRef function of lib/compiler.js, which traverses through a scalar value into the prototype chain, and whose containment guard is missed because currentPath inconsistently holds arrays that coerce to comma-separated strings ("a,b") while the guard checks dot-separated paths ("a.b"). An attacker can inject arbitrary properties onto Object.prototype, affecting every object in the process, by supplying a TOML document whose table path steps through a scalar into __proto__.__proto__, for example [a.b.y.__proto__.__proto__] after y = 1. This requires the application to parse attacker-controlled TOML.
