CISA added CVE-2026-21962 to the Known Exploited Vulnerabilities catalog, giving federal agencies a three‑day deadline to patch a critical Oracle flaw in Oracle HTTP Server and WebLogic Proxy Plug‑in on Windows VMs that can grant full data access. Oracle released patches in January 2026 for affected versions (12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0); private-sector researchers reported active exploitation attempts, underscoring the urgency of patching.
