Summary
rollbar vulnerable to prototype pollution
Details

Impact

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]':'');

Patches

Fixed in version 2.26.5 and 3.0.0-beta5.

Workarounds

If application code directly imports set from rollbar/src/utility, ensure that the second argument does not receive untrusted input.
