Title
dot-access through 1.0.0 Prototype Pollution via set() path argument
Summary
dot-access through 1.0.0 contains a prototype pollution vulnerability that allows attackers to modify Object.prototype by supplying a crafted dotted path to set(). Attackers controlling the path, such as through user-supplied field names, can use __proto__ segments to inject properties into all objects, altering authorization flags and option defaults or crashing the process.
