Summary
The ntharim dot-access package through 1.0.0 contains a prototype pollution flaw in its set() function (CWE-1321). An attacker who controls the dotted path, such as through user-supplied field names, can use __proto__ segments to modify Object.prototype and inject properties into all objects. An unauthenticated remote attacker can alter authorization flags and option defaults or crash the process.
