Description
marshmallow-packages/nova-tiptap is a rich text editor for Laravel Nova based on tiptap. Prior to 5.7.0, 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, the lack of validation on uploaded files (no MIME/type or extension restrictions), and the 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. This vulnerability was fixed in 5.7.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for marshmallow/nova-tiptap. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update marshmallow/nova-tiptap to 5.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-54082 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2025-54082 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2025-54082. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
