Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Airbrake ruby, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The Airbrake Ruby notifier 4.2.3 for Airbrake mishandles the blacklist_keys configuration option and consequently may disclose passwords to unauthorized actors. This is fixed in 4.2.4 (also, 4.2.2 and earlier are unaffected).
