CVE-2026-25895

FUXA is a dashboard-style system used to visualize and monitor industrial or operational processes. This vulnerability is like leaving a “upload” door unlocked: a remote attacker can drop crafted files onto your server without logging in. If they place the right kind of file, it can turn into full control of your server and disrupt your operations.

This matters if you run FUXA (or fuxa-server) for process visualization/monitoring in your business or on behalf of customers. The vulnerability is reachable without authentication and works through the Upload API, so exposure depends on whether that FUXA web service is reachable by an attacker (for example, exposed to the internet) and whether the vulnerable version (through 1.2.9) is deployed.

This is RED because the vulnerability is unauthenticated and remote, and it has been gaining exploitation attention. Attackers can use it to write arbitrary files and achieve remote code execution, so waiting increases the chance of compromise.
