Summary
Oracle WebLogic Server is under active attack following the rapid weaponization of CVE-2026-21962, a critical RCE flaw exploited the same day its exploit code was released. Attackers are using automated tools and VPS infrastructure to target both new and legacy vulnerabilities.
Take Action:
If you're running Oracle WebLogic Server, patch immediately. CVE-2026-21962 is being exploited in the wild on the same day exploit code dropped, and attackers are also chaining older flaws like CVE-2020-14882 and CVE-2017-10271 that still work on unpatched systems. Restrict WebLogic admin console access to internal networks or VPN only, disable protocols you don't need (IIOP, T3), and prioritize getting those patches applied today. These attacks are fully automated, require no login, and give attackers complete control of your server.
