Name of the Vulnerable Software and Affected Versions Rollbar.js versions prior to 2.26.5 Rollbar.js versions 3.0.0-alpha1 through 3.0.0-beta5

Description Rollbar.js provides error tracking and logging from Javascript to Rollbar. A prototype pollution issue exists in the merge() function when application code calls rollbar.configure() with untrusted input. This can lead to prototype pollution. A workaround involves ensuring that values passed to rollbar.configure() do not contain untrusted input.

Recommendations Update to version 2.26.5 or later. Update to version 3.0.0-beta5 or later. Ensure that values passed to rollbar.configure() do not contain untrusted input.
