5.0.0 (2021-10-31)

Bug Fixes

• Fix prototype pollution (#51)

  • The original, non-mutated objects are now returned if any of the keys __proto__, constructor or prototype are used in a json pointer.

  // returns the unmodified input {}
  jsonpointer.set({}, '/foo/__proto__/boo', 'polluted')

  • When passing non-string arrays to a .set operation, an error is thrown:

  // throws `new Error('Invalid JSON pointer. Must be of type string or number.')`
  jsonpointer.set({}, [['__proto__'], ['__proto__'], 'boo'], 'polluted')
