CVE-2026-73647: CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') in quasarframework quasarCVE-2026-73647 0 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. Join the discussion | CVE Database V5 | 08/13/2026, 17:57:09 UTC Added: 08/13/2026, 18:11:59 UTC |
