Oracle Releases September 2026 Critical Security Patch Update Fixing 673 Issues Across Multiple Products
Oracle has released its monthly Critical Security Patch Update (CSPU) on September 15, 2026, providing 673 security patches across numerous product lines.
The CSPU complements the company’s quarterly Critical Patch Update (CPU) by delivering smaller, more frequent fixes for high-priority vulnerabilities. In total, the update resolves 673 issues, corresponding to 672 unique CVEs after deduplication.
Affected products include Oracle Database Server, Oracle Fusion Middleware, Oracle E-Business Suite, Oracle Enterprise Manager, PeopleSoft, Siebel, Oracle Analytics, Oracle Supply Chain, Oracle Commerce, Oracle Communications, and Oracle VM VirtualBox.
According to CVSSv3 base scores, 607 vulnerabilities received a rating of 7.0 or higher. Within this group, 104 issues scored 9.0 or above, including six vulnerabilities rated at the maximum of 10.0, fifteen rated 9.9, and forty-four rated 9.8.
Of particular concern, 247 vulnerabilities allow remote exploitation over the network without requiring authentication.

Vulnerability Management in Atypical Environments: ICS, Networks, IoT, Mobile, Hardware, and ML Systems
Vulnerability management follows the same core process across environments—identify assets, scan, assess risk, prioritize, remediate, and verify—but each domain introduces critical constraints. In industrial control systems, scanning must avoid disrupting physical processes, requiring audit-mode authenticated scans, digital twins for testing, and strict change windows. Network devices frequently suffer from poor segmentation, default SNMP community strings, and exposed management interfaces that enable traffic redirection or configuration tampering. IoT ecosystems remain plagued by default credentials, as demonstrated by the Mirai botnet that took down major DNS infrastructure in 2016, while modern botnets like Reaper and VPNFilter exploit unpatched firmware at massive scale. Machine learning systems face novel threats including prompt injection, prompt leaking, and jailbreaking that can bypass safety controls or exfiltrate training data. Mobile platforms suffer from extreme fragmentation that prevents timely patching of vulnerabilities such as Stagefright, Pegasus, and BlueBorne. Hardware-level flaws like Spectre, Meltdown, and BadUSB demonstrate that even firmware and silicon require coordinated microcode, OS, and application updates.
Google Issues Chrome 153 Security Update Addressing 42 Vulnerabilities Including Three Critical Flaws
Google has released a major security update for its Chrome browser version 153, fixing a total of 42 vulnerabilities. The update includes three critical-severity issues that could allow attackers to execute arbitrary code or cause memory corruption. Patches are now available for Windows, macOS, and Linux platforms, with versions 153.0.8010.48 and 153.0.8010.47. Among the critical fixes are out-of-bounds read in WebGL, use-after-free in Internals, and another use-after-free in Workers. The release also resolves 28 high-severity flaws affecting the V8 JavaScript engine, ServiceWorker, Skia, DOM, PDF, and other components. Medium and low severity issues were addressed as well, bringing the total to 42 vulnerabilities resolved.
Cisco Secure Email Gateway CVE-2026-76461 Critical SQL Injection Flaw Exploited in the Wild for Root Access
Cisco has confirmed active exploitation of CVE-2026-76461, a CVSS 9.8 critical SQL injection vulnerability in Secure Email Gateway. The flaw resides in AsyncOS mail parsing logic and allows unauthenticated attackers to execute arbitrary commands as root simply by sending a specially crafted email. No user interaction, authentication, or workarounds exist, leaving immediate patching as the only mitigation. Affected versions include all releases up to 15.5, 16.0, and 16.5; fixed builds are 15.5.5-014, 16.0.4-302, and 16.5.0-780. Because the gateway sits at the network perimeter with high privileges, successful compromise enables long-term email interception, lateral movement, and internal phishing campaigns. Organizations should examine mail_logs for patterns such as COPY.*TO PROGRAM and cross-check network telemetry for anomalous outbound connections.
How Modern API Attacks Abuse Legitimate Functionality Instead of Exploiting Vulnerabilities
Traditional API incidents once centered on authorization errors, access control issues, SQL injections, and known vulnerability exploitation. Today, many attacks on APIs no longer require finding code flaws; attackers simply use documented methods, valid authorization, and correct parameters at unexpected scale or timing. NGENIX security teams observe three main behavioral patterns: Burst attacks that overload resource-heavy endpoints, Shortwave attacks that exploit race conditions through timed parallel requests, and Carpet Bombing that distributes activity across dozens of endpoints for reconnaissance or scalping. These techniques often bypass WAF because each individual request appears fully compliant with API specifications. Protection is shifting toward behavioral analysis, sliding-window rate limiting, and monitoring of overall client behavior rather than single-request signatures. Real-world cases include sudden catalog scraping during contests and mass reservation of airline seats without purchases, leading to degraded service for legitimate users.
