What it means for a small business
Di-604 Broadband Router is network equipment or remote-access software: the box between your office and the internet. These are a favorite target because breaking one opens the whole office.
If an IT provider set it up, ask them to confirm the firmware version and the date it was updated. If nobody looks after it, that's the bigger problem.
How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 19%, top 3% of all CVEs. That’s high: fix it ahead of everything else on the list. Scored October 28, 2026, updated daily.
Check your own setup
- Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
- Server check: what your web server says about itself, and whether that version has known flaws.
