| タイトル | jsonata-js jsonata 2.2.0 Prototype Pollution |
|---|
| 説明 | JSONata's function binding frame system creates bindings using a plain object ({}) and assigns values with bindings[name] = value without prototype chain validation. The for...in loop in the user bindings handler and createFrameFromTuple traverses the prototype chain, allowing attackers to override built-in functions. A novel bypass exists: passing a hasOwnProperty property in user bindings shadows the inherited Object.prototype.hasOwnProperty, bypassing the lookup() security check. This affects 63 built-in functions including $sum, $count, $eval, etc. |
