Advisories for Composer/Livewire/Livewire package

In Livewire v3 (≤ 3.8.2) and v4 (≤ 4.3.3), a vulnerability allows unauthenticated attackers to execute arbitrary JavaScript in the origin of an affected application in specific scenarios. The issue stems from how certain client-side component state is handled. This vulnerability does not affect prior major versions. Exploitation requires user interaction, but does not require authentication or prior access to the application. The issue does not bypass server-side authorisation and …

In Livewire v3 (≤ 3.6.3), a vulnerability allows unauthenticated attackers to achieve remote command execution in specific scenarios. The issue stems from how certain component property updates are hydrated. This vulnerability is unique to Livewire v3 and does not affect prior major versions. Exploitation requires a component to be mounted and configured in a particular way, but does not require authentication or user interaction.

In livewire/livewire prior to v2.12.7 and v3.5.2, the file extension of an uploaded file is guessed based on the MIME type. As a result, the actual file extension from the file name is not validated. An attacker can therefore bypass the validation by uploading a file with a valid MIME type (e.g., image/png) and a “.php” file extension. If the following criteria are met, the attacker can carry out an …

livewire/livewire versions greater than 2.2.4 and less than 2.2.6 are affected by a data leakage vulnerability. The $this->validate() method, which is expected to return only the validated dataset, was returning all properties of the Livewire component. This regression introduced a security risk, allowing unvalidated data to be exposed, which could lead to unexpected behavior and potential security issues.

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.

Cross-Site Request Forgery (CSRF) vulnerability in livewire before v3.0.4, allows remote attackers to execute arbitrary code getCsrfToken function.
