How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-21504, inspect your project dependencies for Livewire/livewire:

inspect dependencies for livewire/livewire

Analyze the terminal output to locate any version of Livewire/livewire in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.4.9), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Livewire/livewire, 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

Versions of the package livewire/livewire from 3.3.5 and before 3.4.9 are vulnerable to Cross-site Scripting (XSS) when a page uses [Url] for a property. An attacker can inject HTML code in the context of the user's browser session by crafting a malicious link and convincing the user to click on it.
