CyberRota Analysis
AI-GeneratedThe Quasar Framework's public extend() utility in versions prior to 2.22.0 is vulnerable to a prototype pollution attack, allowing attackers to manipulate Object.prototype by recursively copying attacker-controlled object keys. This can lead to various impacts, including logic bypass, unsafe option injection, and potential denial of service in applications that utilize user-controlled objects. Developers using affected versions of the Quasar Framework should prioritize upgrading to version 2.22.0 to mitigate these risks.

Original NVD Description
Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to 2.22.0, the public extend() utility in ui/src/utils/extend/extend.js recursively copied attacker-controlled object keys during extend(true, target, source) deep merges without rejecting an own __proto__ property. The merge could descend into the prototype object and write attacker-controlled properties to Object.prototype in the same JavaScript process. Applications that passed user-controlled or partially user-controlled objects to extend() could experience logic bypass, unsafe default-option injection, denial of service, or other application-specific impact when polluted properties were later consumed. This issue is fixed in version 2.22.0.
