VFC-DMP-5000: Unrestricted Upload of File with Dangerous Type
CVE-2026-33560 is a high-severity unrestricted upload of file with dangerous type vulnerability in VFC-DMP-5000 from Daktronics, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions v8.117.x.x, v9.43.x.x, v10.34.x.x as the first without the flaw, so updating VFC-DMP-5000 to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.44% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
The DMP-5000 file service exposes authenticated arbitrary file upload functionality. There are exposed endpoints which allows authenticated users to upload files of any type without validation. No file extension filtering or content inspection is enforced which allows executable binaries and scripts to be accepted and written directly to the server.

The underlying weakness: Unrestricted Upload of File with Dangerous Type
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
How developers prevent this class of flaw
- Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
- Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically.
