## Executive Summary

Organizations face renewed mass exploitation of critical enterprise software vulnerabilities this quarter, with threat actors demonstrating sophisticated web application firewall bypass techniques against Oracle PeopleSoft (CVE-2026-35273) and active exploitation of Microsoft SharePoint (CVE-2026-65660), WSO2 (CVE-2026-5430), and Roundcube Webmail (CVE-2026-48842) flaws now listed in the CISA Known Exploited Vulnerabilities catalog [ShinyHunters uses WAF bypass trick in Oracle PeopleSoft attacks](https://www.bleepingcomputer.com/news/security/shinyhunters-uses-waf-bypass-trick-in-oracle-peoplesoft-attacks/) [SharePoint RCE and MikroTik RouterOS Flaws Actively Exploited in the Wild](https://thehackernews.com/2026/09/sharepoint-rce-and-mikrotik-routeros.html) [CISA warns of Sharepoint, WSO2, Adobe Commerce flaws exploited in attacks](https://www.bleepingcomputer.com/news/security/cisa-warns-of-sharepoint-wso2-adobe-commerce-flaws-exploited-in-attacks/) [Roundcube Pre-Auth SQL Injection Flaw Actively Exploited in the Wild](https://thehackernews.com/2026/09/roundcube-pre-auth-sql-injection-flaw.html).

Supply chain risk has escalated through compromised third-party GitHub Actions that remained accessible for over a week after re-enablement despite containing malicious Mini Shai-Hulud payloads, while AI agent deployments introduce novel data exposure vectors as evidenced by OpenAI agents uploading user-provided images to third-party hosting services [GitHub Actions re-enabled with Mini Shai-Hulud payload still active](https://www.bleepingcomputer.com/news/security/github-actions-re-enabled-with-mini-shai-hulud-payload-still-active/) [OpenAI's AI agents accidentally uploaded user-provided images to third-party sites](https://www.bleepingcomputer.com/news/artificial-intelligence/openais-ai-agents-accidentally-uploaded-user-provided-images-to-third-party-sites/).

Malware-as-a-service platforms continue to evolve, with Lunex Stealer leveraging AMD driver abuse to disable security monitoring and harvest browser credentials through ClickFix-style social engineering, and a high-severity Elementor WordPress plugin CSRF flaw (CVSS 8.8) enabling unauthenticated administrative account creation [Lunex Stealer Abuses AMD Driver to Disable Security Monitoring and Steal Browser Credentials](https://thehackernews.com/2026/09/lunex-stealer-abuses-amd-driver-to.html) [Elementor CSRF Flaw Lets Attackers Take Over Sites After Admin Clicks Crafted Link](https://thehackernews.com/2026/09/elementor-csrf-flaw-lets-attackers-take.html).

Microsoft has paused the KB5002907 Microsoft 365 update after it deactivated perpetual Office 2016 and 2019 licenses, highlighting operational risk from patch management processes, while industry discourse shifts toward zero-trust architectures for AI agents following intrusion incidents during agent evaluations [Microsoft pauses KB5002907 update after Office license deactivations](https://www.bleepingcomputer.com/news/microsoft/microsoft-365-kb5002907-update-paused-after-office-license-deactivations/) [Zero Trust for AI Agents Starts With Fixing Zero Visibility](https://thehackernews.com/2026/09/zero-trust-for-ai-agents-starts-with.html).

## Recommendations for Action

1. **Immediate Patching Sprint** — Deploy emergency patches for CVE-2026-35273 (Oracle PeopleSoft), CVE-2026-65660 (SharePoint), CVE-2026-5430 (WSO2), and CVE-2026-48842 (Roundcube) within 72 hours per CISA KEV guidance; validate WAF rule effectiveness against URL-encoding bypass variants [ShinyHunters uses WAF bypass trick in Oracle PeopleSoft attacks](https://www.bleepingcomputer.com/news/security/shinyhunters-uses-waf-bypass-trick-in-oracle-peoplesoft-attacks/) [SharePoint RCE and MikroTik RouterOS Flaws Actively Exploited in the Wild](https://thehackernews.com/2026/09/sharepoint-rce-and-mikrotik-routeros.html) [CISA warns of Sharepoint, WSO2, Adobe Commerce flaws exploited in attacks](https://www.bleepingcomputer.com/news/security/cisa-warns-of-sharepoint-wso2-adobe-commerce-flaws-exploited-in-attacks/) [Roundcube Pre-Auth SQL Injection Flaw Actively Exploited in the Wild](https://thehackernews.com/2026/09/roundcube-pre-auth-sql-injection-flaw.html).

2. **Software Supply Chain Hardening** — Audit all third-party GitHub Actions in CI/CD pipelines; pin actions to immutable commit SHAs; implement policy-as-code to block unpinned or unverified actions; monitor for Mini Shai-Hulud indicators [GitHub Actions re-enabled with Mini Shai-Hulud payload still active](https://www.bleepingcomputer.com/news/security/github-actions-re-enabled-with-mini-shai-hulud-payload-still-active/).

3. **AI Agent Data Governance** — Enforce egress controls and data loss prevention for autonomous agent workloads; require explicit allowlists for external API destinations; implement session-level audit logging for agent file operations [OpenAI's AI agents accidentally uploaded user-provided images to third-party sites](https://www.bleepingcomputer.com/news/artificial-intelligence/openais-ai-agents-accidentally-uploaded-user-provided-images-to-third-party-sites/) [Zero Trust for AI Agents Starts With Fixing Zero Visibility](https://thehackernews.com/2026/09/zero-trust-for-ai-agents-starts-with.html).

4. **Endpoint Detection Enhancement** — Update EDR signatures for Lunex Stealer AMD driver abuse patterns; deploy application control policies restricting unsigned driver loads; conduct phishing simulations incorporating ClickFix CAPTCHA lures [Lunex Stealer Abuses AMD Driver to Disable Security Monitoring and Steal Browser Credentials](https://thehackernews.com/2026/09/lunex-stealer-abuses-amd-driver-to.html).

5. **Web Asset Remediation** — Update Elementor Website Builder plugin to patched version immediately; audit WordPress admin accounts for unauthorized additions; implement CSRF token validation at WAF layer [Elementor CSRF Flaw Lets Attackers Take Over Sites After Admin Clicks Crafted Link](https://thehackernews.com/2026/09/elementor-csrf-flaw-lets-attackers-take.html).

6. **Patch Validation Protocol** — Establish pre-deployment testing for Microsoft 365 updates in staging environments covering perpetual license scenarios; maintain rollback playbooks for license-impacting changes [Microsoft pauses KB5002907 update after Office license deactivations](https://www.bleepingcomputer.com/news/microsoft/microsoft-365-kb5002907-update-paused-after-office-license-deactivations/).
