Today’s Field Note
Three items cleared the bar today, and two of them are already being fired at live targets. Attackers are exploiting CVE-2026-6875 in the ServiceNow AI Platform for code execution (per Defused), so if you run ServiceNow, assume it is on someone’s list. The WP2Shell pair, CVE-2026-60137 and CVE-2026-63030, went from disclosure to in-the-wild exploitation with the usual WordPress speed. And F5’s NGINX flaw, CVE-2026-42533, is an unauthenticated heap overflow reachable with crafted HTTP requests: crash today, likely RCE tomorrow, and it sits on the exact boxes facing the internet. None of these wait for your change window.
Today’s Action
- Patch ServiceNow AI Platform for CVE-2026-6875 now and review logs for unexpected code execution or new integration/script activity.
- Update NGINX to 1.30.4 (stable) or 1.31.3 (mainline), and NGINX Plus to 37.0.3.1, prioritizing internet-facing instances.
- Audit WordPress installs for the plugin/theme tied to WP2Shell (CVE-2026-60137, CVE-2026-63030), patch, and hunt for dropped web shells.
- Pull WAF and access logs for anomalous POSTs and malformed HTTP requests against these three surfaces from the last two weeks.
- Confirm your NGINX worker processes are not silently crash-looping, an early signal someone is testing the overflow.
