CVE-2025-68436: Craft CMS vulnerable to potential information disclosure via unchecked asset relocation

Craft is a platform for creating digital experiences. In versions 5.0.0-RC1 through 5.8.20 and 4.0.0-RC1 through 4.16.16, authenticated users on a Craft installation could potentially expose sensitive assets via their user profile photo via maliciously crafted requests. Users should update to the patched versions (5.8.21 and 4.16.17) to mitigate the issue.

Root Cause Analysis

The vulnerability allows authenticated users to expose sensitive assets by manipulating their user profile photo. The provided patch addresses this by modifying the src/elements/User.php file.

The key change is the addition of the safeAttributes() method to the craft\elements\User class. This method explicitly removes the photoId attribute from the list of 'safe' attributes for mass assignment. In the Yii framework (which Craft CMS is built on), attributes listed as 'safe' can be updated en masse from user-provided data (e.g., a form submission). By removing photoId from this list, the patch prevents a user from directly setting the ID of their profile photo in a request.

This implies that the vulnerability existed because a user could craft a request to update their profile and set the photoId to an arbitrary asset ID. If the application didn't properly verify that the user had legitimate access to that asset, it could lead to the asset's information being exposed through the user's profile.

The safeAttributes function is the direct mitigation. The underlying vulnerability is in the controller action that processes user profile updates, which previously allowed the photoId to be set without sufficient validation. While the controller is not shown in the patch, the change in the User model is the critical piece of evidence and the most precise indicator of the vulnerability's location in the codebase.
