Oracle July 2026 CPU, nine unauthenticated CVSS 10.0 flaws in Fusion Middleware, with NCSC-NL assessing large-scale abuse as very likely in the short term

Oracle's quarterly Critical Patch Update is normally exactly what the routine patch cycle exists to absorb, and most of the July 2026 release is. What separates this one is a concentration that two national CERTs judged worth their own advisories inside the following week. On Oracle's own account, "This Critical Patch Update contains 355 new security patches , plus additional third party patches noted below, for Oracle Fusion Middleware. 219 of these vulnerabilities may be remotely exploitable without authentication" (Oracle, 2026-07-16); CSOonline reports the same split, noting that "Fusion Middleware was particularly hard hit, with new security patches for 355 security vulnerabilities, 219 of them remotely exploitable without authentication, meaning they can be exploited over a network without requiring user credentials" (CSOonline, 2026-07-22).

Two counts differ between the sources, and the difference is worth knowing before you brief anyone. NCSC-NL states that the most severe vulnerabilities, nine of them, received the highest score of 10.0 (NCSC-NL, 2026-07-22), while press coverage says ten. Both are right about their own object: Oracle's Fusion Middleware risk matrix carries ten rows at base score 10.0 but only nine distinct CVE identifiers, because CVE-2026-60365 appears twice, once under Oracle HTTP Server and once under the WebLogic Server Proxy Plug-in (Oracle, 2026-07-16). NCSC-NL's total for the component also differs from Oracle's, 345 fixes against Oracle's 355. Nine distinct maximum-severity CVEs is the figure to use.

Each of the nine is reachable over a standard network protocol (HTTP, LDAP, SOAP, or raw TCP in Oracle Coherence's case) with no authentication and no user interaction. NCSC-NL's advisory lists the maximum-severity CVE identifiers, among them CVE-2026-47056 and CVE-2026-60217 (NCSC-NL, 2026-07-22); it does not itself pair those identifiers with products, so the pairing, the component names and the affected versions all come from Oracle's risk matrix rather than the advisory, Data Integrator 12.2.1.4.0 and 14.1.2.0.0 in the Rest Service component, and Coherence Core 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0 (Oracle, 2026-07-16). The remaining maximum-severity cases sit across Oracle Access Manager, HTTP Server, Platform Security for Java, WebCenter Content, Service Delivery Platform, Unified Directory and the WebLogic Server Proxy Plug-in. On the database side CVE-2026-61211 (CVSS 9.9) abuses DBMS_CLOUD to reach full server control, though that one is post-authentication.

The escalation is the CERT assessment rather than any observed activity. NCSC-NL's advisory states that "Because of the large number and the severity of these vulnerabilities, the NCSC considers it very likely that large-scale abuse will take place in the short term" (NCSC-NL, 2026-07-22), and CERT-FR published its own advisory the following day (CERT-FR, 2026-07-23). To be precise about what is and is not known: there is no confirmed in-the-wild exploitation of any of the new CVEs, no public proof-of-concept code, and no reported scanning specific to them. This is a forward-looking assessment by two national authorities about an exposure class with a long history of rapid weaponisation, not a report of an active campaign.

Triage: with no public exploit detail there is no behavioural signature specific to these CVEs, and inventing one would be guesswork. What is available is exposure telemetry: enumerate which Fusion Middleware listeners answer from outside the perimeter, and in web-server and application logs for those hosts, treat unauthenticated requests to administrative or REST service paths from unfamiliar source ranges as the class worth reviewing while patching proceeds. Note that Coherence's cluster protocol is raw TCP rather than HTTP, so HTTP-layer inspection will not see it, that exposure has to be established from network policy rather than from application logs.
