How do I mitigate CVE-2025-54082 if there is no patch (or I can't update yet)?

Treat uploaded files as untrusted until proven otherwise: validate the actual content type rather than the supplied extension, store uploads outside the web root on a volume mounted without execute permission, and rename them to server-generated identifiers so an attacker cannot choose the path a request will later resolve.

Is CVE-2025-54082 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-54082 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Exploitation Status

No confirmed exploitation observed yet

CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.
CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

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.
