Developed by CISA, the National Security Agency (NSA) and international partners, this joint guidance contains best practices for software manufacturers and online service providers to design and implement a coordinated vulnerability disclosure (CVD) program for working with external security researchers that includes a clear vulnerability disclosure policy (VDP) and process for triaging, remediating and assigning Common Vulnerabilities and Exposures (CVE) identifiers to reported vulnerabilities. The guidance also provides considerations for leveraging third-party intermediaries, like CISA or other national computer security incident response teams, to substitute or supplement a CVD program. By implementing a robust CVD program aligned with this guidance, organizations can work transparently and collaboratively with security researchers to remediate vulnerabilities, build constructive relationships, enhance product security while improving vulnerability management processes, and demonstrate their dedication to protecting customers.

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2023-4346 KNX Association KNX Protocol Connection Authorization Option 1 Overly Restrictive Account Lockout Mechanism Vulnerability CVE-2026-46817 Oracle E-Business Suite Improper Privilege Management Vulnerability These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria. Aware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA’s KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.

Legal Notice and Terms of Use This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy). Recommended Practices CISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolate them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

Update July 16, 2026: CISA has updated this Alert to reflect the addition of CVE-2026-58644 to its Known Exploited Vulnerabilities (KEV) Catalog on July 16, 2026. CISA is aware of active exploitation of vulnerabilities CVE-2026-32201, CVE-2026-45659, CVE-2026-56164, and CVE-2026-58644, enabling cyber threat actors to gain unauthorized access to on-premises SharePoint Server instances. These vulnerabilities affect all supported on-premises SharePoint Server versions (Subscription Edition, 2019, and 2016) and involve establishing remote code execution (RCE) and post-exploitation activities, such as stealing Internet Information Services (IIS) machine keys and performing deserialization techniques, to gain persistence and deploy malware. Organizations should monitor affected SharePoint Servers closely for any signs of exploitation or unusual activity. Additionally, the following newly disclosed CVE is not yet known to have been exploited, but Microsoft has identified it as posing a potential risk if left unpatched: CVE-2026-55040 CISA urges organizations to detect and remediate a potential compromise by implementing the following recommendations: Apply the latest patches and security updates from Microsoft, verify that installation completes successfully, and shorten patching cycles when possible. Verify that Antimalware Scan Interface (AMSI) integration is enabled for each SharePoint web application. Follow Microsoft’s Configure AMSI integration with SharePoint Server guidance to ensure proper configuration and select the “Full Mode” option for the Request Body Scan Mode, where feasible. When compromise is expected, use the following AMSI and Microsoft Defender Antivirus (MDAV) detections, and implement your organization’s incident response plan for any positive detections: AMSI: Exploit:Script/SuspSignoutReqBody.A – request body scanning; SharePoint Server Subscription only; Microsoft has blocked observed attempts. AMSI: Exploit:Script/ToolPaneAuthBypass.A – request header scanning; SharePoint Server 2016, 2019, and Subscription Edition. AMSI: Exploit:Script/ToolPaneAuthBypass.C – RCE coverage; SharePoint Server 2016, 2019, and Subscription Edition. MDAV: Backdoor:MSIL/LeakFang.A!dha – post-exploitation activity alert involving IIS-protected secrets. In addition, CISA recommends that organizations implement the following SharePoint Server hardening measures: Before rotating IIS machine keys, hunt for and remediate any intrusion artifacts, including machine-key harvesters, that could allow for the keys to be stolen again. Review Microsoft’s Improved ASP.NET view state security and key management for best practices. Establish tailored logging mechanisms to detect and monitor exploitation activities. Review telemetry for anomalous requests, suspicious SharePoint worker-process activity, webshells, and machine-key access. For more information, see CISA’s Best Practices for Event Logging and Threat Detection. Avoid exposing SharePoint Servers directly to the internet unless necessary; and if necessary, only configure a SharePoint Server behind a Layer 7 reverse proxy or equivalent application-layer security control that requires authentication and can inspect and filter requests. Block external access to SharePoint Central Administration, restrict farm and database communications to required systems, and review Microsoft’s SharePoint Server security-hardening guidance for role-specific ports, services, and Web.config settings. CISA urges users and administrators to review the Alert UPDATE: Microsoft Releases Guidance on Exploitation of SharePoint Vulnerabilities and apply necessary updates.
