### Impact Prototype pollution vulnerability in merge(). If application code calls `rollbar.configure()` with untrusted input, prototype pollution is possible. ### Patches Fixed in 2.26.5 and 3.0.0-beta5. ### Workarounds Ensure that values passed to `rollbar.configure()` do not contain untrusted input. ### References Fixed in https://github.com/rollbar/rollbar.js/pull/1394 (2.26.x) and https://github.com/rollbar/rollbar.js/pull/1390 (3.x)
