🛡 CISA Known Exploited Vulnerabilities

There is no 100% safe environment

Every entry above was, at some point, a patch an organisation hadn't yet applied. No system connected to a network is ever perfectly safe — new flaws are found constantly, and attackers actively hunt for the gap between a vulnerability's disclosure and its remediation. The goal isn't an unreachable "zero risk"; it's shrinking that gap and limiting what a single successful exploit can reach.

What actually reduces the risk

• Patch by exploitability, not just severity — a CVE on this list is being used right now, so it jumps the queue ahead of a higher CVSS score that isn't.
• Keep an accurate, current inventory of internet-facing software and versions — you can't patch what you don't know you're running.
• Segment networks and apply least-privilege access, so one compromised system doesn't hand over the whole environment.
• Keep offline, tested backups — the single biggest factor in surviving a ransomware incident without paying.
• Monitor continuously (SIEM/EDR with real analysts) so exploitation is caught in minutes, not discovered months later.
• Rehearse your incident response plan before you need it — the first time responders read the runbook shouldn't be during a live breach.
