The Wednesday Brief — free edition — Week 23
this week: 2 items worth knowing · read time: ~4 min
1. Fortinet firewalls. If your office VPN runs on a FortiGate, this is your week to patch. CVE-2026-21704 (illustrative) landed in CISA’s exploited list, which means it’s being used in real attacks, mostly against the SSL-VPN portal. Update FortiOS, or turn the web portal off until you can. If an IT provider manages your firewall, forward them this paragraph.
2. Windows Server, June updates. This month’s cumulative update fixes a privilege-escalation flaw (CVE-2026-20512 (illustrative)) with public proof-of-concept code. If you run your own servers, confirm June updates are installed. One sentence to whoever patches: “confirm June CU on the servers.”
Everything else we reviewed this week didn’t clear the bar for a typical small-business stack. The paid version of this email is matched to your exact inventory — it would tell you whether these two apply to you, and log the answer.
