A prototype pollution vulnerability has been identified in svgdotjs svg.js versions through 3.2.5. The issue arises in the npm Package API, specifically within the EventTarget.on() function. The vulnerability allows for improper control over the modification of object prototype attributes, which can be exploited remotely.
It is recommended to reject event names that could cause prototype pollution before they are processed by the EventTarget.on() method. Specifically, names like '__proto__', 'constructor', and 'prototype' should be filtered out to prevent unauthorized modifications to the JavaScript object prototypes.
