CyberRota Analysis
AI-GeneratedThe vulnerability affects the Livewire framework for Laravel, specifically versions 3.0.0-beta.1 through 3.8.3 and 4.3.4, allowing unauthenticated attackers to exploit the dot-notated query-string parser to execute arbitrary JavaScript in the context of the affected application. This exploitation requires user interaction and can lead to unauthorized manipulation of client-side state, but does not bypass server-side authorization. Organizations using affected versions should prioritize updating to versions 3.8.3 or 4.3.4 to mitigate this risk.

Original NVD Description
Livewire is a full-stack framework for Laravel. From 3.0.0-beta.1 until 3.8.3 and 4.3.4, the dot-notated query-string parser in js/plugins/history/index.js, including fromQueryString() and insertDotNotatedValueIntoData(), accepts the __proto__, constructor, and prototype path segments and creates inherited objects. Client-side state handlers then access effects.html, effects.js, effects.xjs, and effects.scripts without Object.prototype.hasOwnProperty.call(), allowing inherited attacker-controlled state to be treated as trusted effects. An unauthenticated attacker can craft a URL that, when opened by a user, executes arbitrary JavaScript in the affected application's origin. Exploitation requires user interaction and does not bypass server-side authorization or grant privileges beyond the affected user. This issue is fixed in versions 3.8.3 and 4.3.4.
