Oracle's September 2026 Critical Security Patch Update carries fifty unauthenticated CVSS 9.8+ flaws, concentrated in Fusion Middleware's identity, forms, directory and portal components, plus E-Business Suite, Hyperion, Analytics, Enterprise Manager, Communications and Supply Chain products

Oracle published its September 2026 Critical Security Patch Update on 2026-09-15 (Rev 1, initial release) with 673 new security patches across its product families; Oracle Fusion Middleware alone accounts for 153 of them, and Oracle states that "78 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials" (Oracle, 2026-09-15). Six flaws in the release carry a CVSS 3.1 base score of 10.0 in Oracle's own risk matrix with Attack Vector Network, Attack Complexity Low, Privileges Required None, User Interaction None and Scope Changed, meaning an unauthenticated request across the network reaches high confidentiality and integrity impact and crosses a security boundary (the first five also reach high availability impact; Hyperion Financial Management's is rated none): CVE-2026-83021 in the Web Container of Oracle WebLogic Server over HTTP, CVE-2026-71133 in the Authentication Engine of Oracle Access Manager over HTTP, CVE-2026-83099 in Oracle Forms Services over HTTP, CVE-2026-83059 in the OID LDAP Server of Oracle Internet Directory over LDAP, CVE-2026-83020 in the centralized third-party jars of Oracle Platform Security for Java over HTTP, and CVE-2026-87230 in the Security component of Oracle Hyperion Financial Management over HTTP (Oracle, 2026-09-15). The Netherlands' national cyber-security centre relayed the release's 153 Fusion Middleware fixes as advisory NCSC-2026-0372 on 2026-09-16 and rated both likelihood and damage high (NCSC-NL, 2026-09-16).

The Critical Security Patch Update is Oracle's second, higher-frequency release line, published alongside the quarterly cumulative Critical Patch Update rather than replacing it: Oracle describes it as providing "targeted, high-priority security fixes in a smaller, more focused format, making them easier to apply with minimal disruption" and says these updates "complement Oracle’s existing quarterly cumulative Critical Patch Updates (CPUs)" (Oracle, 2026-09-15). Oracle now releases security patches on the third Tuesday of each month. Its next four dates are the Critical Patch Update of 20 October 2026, Critical Security Patch Updates on 17 November and 15 December 2026, and the Critical Patch Update of 19 January 2027 (Oracle, 2026-09-15). A patch calendar built only on the quarterly dates misses the releases in between.

Oracle discloses no exploitation technique, no proof-of-concept status and no in-the-wild activity for any of the fifty unauthenticated flaws, and no source names an exploited flaw (Oracle, 2026-09-15). What forces the timeline is the shape of the flaws: every one is reachable by an unauthenticated network request with no user interaction (Oracle, 2026-09-15). The six rated CVSS 10.0 sit in components that front other systems or hold what they rely on: WebLogic's web container, Access Manager's authentication engine, an Internet Directory LDAP listener, Forms Services, the shared Java security jars underneath Fusion Middleware, and Hyperion Financial Management's security component (Oracle, 2026-09-15). Where an organization runs its single sign-on, directory or application-server tier on these Fusion Middleware components, a Scope Changed rating on an authentication engine means the compromise does not stay inside the component that carries the flaw.

This Critical Security Patch Update contains 153 new security patches for Oracle Fusion Middleware.

78 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

A Critical Security Patch Update (CSPU) provides targeted, high-priority security fixes in a smaller, more focused format, making them easier to apply with minimal disruption.

This Critical Security Patch Update contains 159 new security patches for Oracle E-Business Suite. 19 of these vulnerabilities may be remotely exploitable without authentication

Oracle's September 2026 risk matrix lists eight further unauthenticated CVSS 9.8 flaws (Attack Vector Network, Privileges Required None, User Interaction None) beyond the six CVSS 10.0 flaws, across four further product families (Oracle, 2026-09-15). Oracle E-Business Suite carries 159 new patches, of which 19 are remotely exploitable without authentication: "This Critical Security Patch Update contains 159 new security patches for Oracle E-Business Suite. 19 of these vulnerabilities may be remotely exploitable without authentication" (Oracle, 2026-09-15). Three of those nineteen reach CVSS 9.8 with no further precondition: CVE-2026-83327 in the Applications Framework's Personalization component over SOAP, CVE-2026-83452 in Document Management and Collaboration's Internal Operations component over HTTP, and CVE-2026-83462 in the Mobile Application Server's MWA Terminal Server component over TCP, all affecting versions 12.2.3 through 12.2.15. Oracle Business Intelligence Enterprise Edition (Oracle Analytics, 50 new patches, 8 unauthenticated) carries CVE-2026-83283 in its Platform Security component (version 12.2.1.4.0, over HTTP). Oracle Enterprise Manager carries CVE-2026-41635 (Agent Next Gen / Apache Mina component, versions 13.5/24.1, over HTTP, the same patch also fixing CVE-2026-41409 and CVE-2026-42779) and CVE-2026-83355 (Enterprise Manager for Fusion Middleware's Metrics component, same versions). Oracle Communications (31 new patches, 23 unauthenticated) carries CVE-2026-44024 (Unified Assurance's Core/Fluentd component, versions 6.1.1-7.0.0, the same patch also fixing CVE-2026-44025, CVE-2026-44160 and CVE-2026-44161) and CVE-2026-17544 (Unified Assurance's Core/PHP component, version 7.0.0).

On the same bar (Access Vector Network, Privileges Required None, User Interaction None, "Remote Exploit without Auth." Yes), the matrix lists thirty-two further CVSS 9.8 flaws inside the Fusion Middleware product line, beyond the single CVSS 10.0 flaw in each of five of its components. Access Manager carries four more (CVE-2026-73950, CVE-2026-73947, CVE-2026-73940, CVE-2026-47065, the Authentication Engine and a Third Party/Apache Mina component, over HTTP or T3/IIOP or TCP/IP). Forms carries five more (CVE-2026-83094, -83095, -83098, -83100, -83108, all in Forms Services/C-S/ Charmode over HTTP). Internet Directory carries five more (CVE-2026-83054, -83060, -83061, -83062, -83066, the OID LDAP Server over LDAP or T3/IIOP). Platform Security for Java carries two more (CVE-2026-82994 over LDAP, CVE-2026-82995 over SOAP, both in the centralized third-party jars). WebLogic Server carries three more (CVE-2026-70756, -70757, -70748, its Core component over T3/IIOP). The remaining thirteen are in other Fusion Middleware components: Data Integrator (CVE-2026-83232, Console/ Repository Explorer, HTTP), Identity Manager (CVE-2026-70913 Core and CVE-2026-83042 OIM Legacy UI, both HTTP), JDeveloper (CVE-2026-73961, ADF Faces, HTTP), WebCenter Enterprise Capture (CVE-2026-83339, Client Bundle, HTTP), WebCenter Portal (CVE-2026-73956 Composer and CVE-2026-73953/-73963 Portlet Services, all HTTP), WebCenter Sites (CVE-2026-83035, -83036, -83037, HTTP) and Service Delivery Platform (CVE-2026-83000 and -83151, Messaging Enabler, over HTTP or SOAP) (Oracle, 2026-09-15). Outside Fusion Middleware there are four more: two further Hyperion Financial Management flaws (CVE-2026-87188 over HTTP, CVE-2026-87184 over SQL, alongside the original CVE-2026-87230), one more in Oracle Analytics (CVE-2026-83269 in BI Publisher's BI Platform Security component, over HTTP, alongside CVE-2026-83283 in Business Intelligence Enterprise Edition), and one in Oracle Supply Chain's Product Lifecycle Analytics (CVE-2026-83261, Core component, HTTP). The total for the release is fifty unauthenticated CVSS 9.8-10.0 flaws.

None of the fifty is reported exploited by Oracle or any other source, and none appears in the CISA Known Exploited Vulnerabilities catalog. Oracle E-Business Suite deserves early patching despite the absence of exploitation reporting: Cl0p exploited an earlier Oracle EBS zero-day from early August 2025 to steal files from many organizations (BleepingComputer, 2026-08-17), and an estate running EBS 12.2.3-12.2.15 should treat its three unauthenticated flaws as an extension of that same exposure class rather than a routine patch-cycle item. By count, the exposure is dominated by Fusion Middleware: Access Manager, Forms and Internet Directory alone carry five to six unauthenticated CVSS 9.8-10.0 flaws each, and an estate that patched only the six CVSS 10.0 components has patched a small fraction of what this release actually contains.

Oracle's risk matrix lists fifty unauthenticated, no-interaction flaws at CVSS 9.8 to 10.0 in this release, not six, and none is reported exploited (Oracle, 2026-09-15). Oracle gives no vulnerability class for any of them, so the earlier authentication-bypass label and the triage guidance that assumed an exploitation mechanism are withdrawn. Oracle now patches monthly, and its next releases are the Critical Patch Update of 20 October 2026 and Critical Security Patch Updates on 17 November and 15 December 2026 (Oracle, 2026-09-15). NCSC-NL relayed the 153 Fusion Middleware fixes and rated likelihood and damage high (NCSC-NL, 2026-09-16). The 2025 E-Business Suite campaign was Cl0p's exploitation of an earlier zero-day (BleepingComputer, 2026-08-17).
