Advisories for Npm/Rollbar package

Prototype pollution vulnerability in merge(). If application code calls rollbar.configure() with untrusted input, prototype pollution is possible.

Prototype pollution potential with the utility function rollbar/src/utility.set(). No impact when using the published public interface. If application code directly imports set from rollbar/src/utility and then calls set with untrusted input in the second argument, it is vulnerable to prototype pollution. POC: const obj = {}; require("rollbar/src/utility").set(obj, "proto.polluted", "vulnerable"); console.log({}.polluted !== undefined ? '[POLLUTION_TRIGGERED]':'');

rollbar is a package designed to effortlessly track and debug errors in JavaScript applications. This package includes advanced error tracking features and an intuitive interface to help you identify and fix issues more quickly. A Prototype Pollution vulnerability in the utility.set function of rollbar v2.26.4 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.
