Security Articles

Stay ahead of emerging threats with expert analysis from 148 published security articles, vulnerability reports, and cybersecurity insights — updated daily with the latest CVEs, threat actor campaigns, and security advisories. As of Sunday, July 5, 2026, the most urgent items for production stacks: F5 has patched two flaws in NGINX — the web-server software that runs a large share of the internet — that together hand a remote attacker unauthenticated RCE, meaning remote code execution, where an intruder runs their own commands on your server without ever logging in; if any of your public websites or apps sit behind NGINX, apply F5's fix now, because a compromised web server is a direct path to customer data and downtime. Microsoft is still racing a patch for the "RoguePlanet" Defender zero-day, CVE-2026-50656 — a zero-day is a flaw being exploited before the vendor has a fix ready — which lets an attacker gain SYSTEM, the highest level of control on a Windows machine, turning the very tool meant to protect the endpoint into the foothold; watch for Microsoft's out-of-band update and tighten monitoring in the meantime. Three FortiSandbox flaws are under active exploitation, with attackers chaining an authentication bypass (slipping past the login) with command injection (feeding the device commands it was never meant to run) to seize the appliance that is supposed to detonate and catch malware — a reminder that even security gear needs patching. A Palo Alto Networks GlobalProtect flaw, CVE-2026-0257, remains under active exploitation — an authentication bypass in the GlobalProtect VPN portal (the gateway your remote staff log in through) that lets an attacker reach your internal network without valid credentials, so apply Palo Alto's fix and review the portal for unfamiliar sessions. And the Oracle PeopleSoft zero-day CVE-2026-35273 is still being used by the ShinyHunters extortion crew to break into universities and large enterprises, so apply Oracle's emergency fix the moment it lands and watch for unfamiliar logins. If your business runs NGINX, Windows Defender, Fortinet appliances, Palo Alto GlobalProtect VPN, or Oracle PeopleSoft, these advisories require action now — start with the article-level remediation steps below.
