Description

A prototype pollution vulnerability was found in UglifyJS, stemming from the DEFNODE function in ast.js via the name variable. Exploiting this flaw involves adding or altering properties of the Object.prototype through a "proto" or constructor payload, enabling an attacker to execute arbitrary code or causing a denial of service on the system.

Statement
