GHSA-96c2-h667-9fxp: nova-tiptap has Unauthenticated Arbitrary File Upload Vulnerability
A vulnerability was discovered in the marshmallow-packages/nova-tiptap Laravel Nova package that allows unauthenticated users to upload arbitrary files to any Laravel disk configured in the application.
The vulnerability is due to: • Missing authentication middleware (Nova and Nova.Auth) on the /nova-tiptap/api/file upload endpoint • Lack of validation on uploaded files (no MIME/type or extension restrictions) • Ability for an attacker to choose the disk parameter dynamically
This means an attacker can craft a custom form and send a POST request to /nova-tiptap/api/file, supplying a valid CSRF token, and upload executable or malicious files (e.g., .php, binaries) to public disks such as local, public, or s3. If a publicly accessible storage path is used (e.g. S3 with public access, or Laravel’s public disk), the attacker may gain the ability to execute or distribute arbitrary files — amounting to a potential Remote Code Execution (RCE) vector in some environments.
