Oracle July 2026 CPU — 1,434 CVEs, 1,449 Patches: The Largest Quarterly Security Release in Oracle's History and What Every UK Business Running Oracle Must Do This Week
Oracle released its July 2026 Critical Patch Update on 21 July — the largest quarterly security release in the company's history, addressing 1,434 CVEs across 334 products with 1,449 patches, ~600 of which are remotely exploitable without authentication. A CVSS 9.8 PeopleSoft zero-day (CVE-2026-35278) was already exploited by ShinyHunters to breach 100+ organisations before this fix shipped — making this the most urgent Oracle patching cycle for UK businesses since the 2026 EBS payments exploit.
