CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.

• CVE-2026-86950 Apple Multiple Products Out-of-Bounds Write Vulnerability

This type of vulnerability is a frequent attack vector for malicious cyber actors and poses 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.

CISA is amplifying Citrix’s disclosure of eight new vulnerabilities affecting Citrix NetScaler ADC and Citrix NetScaler Gateway products: CVE-2026-88771, CVE-2026-88772, CVE-2026-88773, CVE-2026-88774, CVE-2026-88775, CVE-2026-88776, CVE-2026-88777, and CVE-2026-88778. 

CISA has added CVE-2026-88771 and CVE-2026-88772 to its Known Exploited Vulnerabilities (KEV) Catalog. Both are critical, zero-day vulnerabilities that can independently enable remote code execution. CISA has received reports and partner threat intelligence confirming that threat actors are actively exploiting these vulnerabilities globally.

Because updating Citrix NetScaler deployments can be complex and may require downtime, CISA is issuing this Alert to help organizations assess exposure, prioritize mitigation, and account for these vulnerabilities into their risk-management activities. 

Given the potential consequences of successful exploitation and the fact that malicious actors are exploiting at least some of these vulnerabilities, CISA urges users and administrators to review Citrix’s advisories. If possible, users are encouraged to check for indication of compromise prior to patching. Citrix has made indicators of compromise available through NetScaler Console and published additional guidance in their recent publication, Security Bulletin for CVE-2026-88771 through CVE-2026-88778, to support organizations in assessing potential compromise. Should your organization suspect compromise, it is important to preserve forensic evidence prior to applying updates, as updates may result in loss of forensic visibility.

Introduction

The Federal Bureau of Investigation (FBI) and Cybersecurity and Infrastructure Security Agency (CISA)—hereafter referred to as the “authoring agencies”—have published this fact sheet to highlight considerations for critical infrastructure entities to reduce risk and minimize vulnerabilities when working with third-party industrial control system (ICS) integrators.

ICS is an umbrella term referring to integrated networks of hardware and software designed to monitor and automate physical processes, encompassing specialized control systems and devices, such as supervisory control and data acquisition (SCADA) systems and programmable logic controllers. Third-party integrators provide varying types of services for ICS, such as control system design, installation, operational data analysis, device support and service, and daily operational control.

Critical infrastructure owners and operators should maintain caution when granting third-party ICS integrators high levels of access or control over industrial processes, ensuring the principle of least privilege (PoLP), is applied. PoLP within OT environments lends itself to granting users, processes, and systems only the minimum access necessary to perform their assigned tasks, and no more. PoLP is designed to protect owners and operators. Not adopting principles such as PoLP could expose owners and operators to malicious cyber actors seeking to compromise critical infrastructure, possibly providing sensitive access to pathways that actors can exploit to cause disruptive and destructive effects to equipment and critical functions. 

Critical infrastructure owners and operators should action the recommendations in this fact sheet to work with integrators to ensure secure practices and frameworks are put in place to reduce the risk of malicious actors exploiting third-party accesses to compromise critical infrastructure operational environments.

Examples of Risk and Exploitation

Much like IT systems, using third-party ICS integrators in critical infrastructure may inadvertently introduce security issues to a customer environment by exposing systems and services not pre-configured to the customer’s security requirements. Critical infrastructure owners and operators that rely on third-party integrators for system design face supply chain risks if integrators and owners and operators do not collectively enforce clear requirements for the secure procurement and handling of system components. Furthermore, third-party integrators that operate and host data outside of the United States may pose additional risks, as they may be subject to different data storage and management laws that do not meet the security needs of U.S. critical infrastructure entities.

According to FBI technical analysis, between March and April 2025, malicious foreign cyber actors gained access to the network of a U.S. industrial automation solutions company that offered services—such as system integration, engineering consulting, and SCADA programming—for industrial customers, including power utilities and transportation entities. While on the network, threat actors searched terms, including “customers” and “SCADA,” and created nine .zip files consisting of approximately 800 files for presumed exfiltration, including customer SCADA information, ICS device details, and other schematics. Malicious cyber actors could leverage the exfiltrated information to later conduct disruptive attacks against operational environments and disrupt critical services.

Recommendations to Assess Risk

Critical infrastructure owners and operators should make risk-informed decisions when considering introducing third-party integrators into their networks and operations, guided by a robust understanding of the organizational risks posed by providing sensitive access to their systems.

Organizations should routinely conduct risk assessments to evaluate contracts that involve access to industrial systems, to determine impacts to the organization’s data autonomy and process controls. Risk assessments should address hardware and software supply chain vulnerabilities introduced by integrator equipment, as well as the IT and OT security of these devices and their associated networks. When considering implementing foreign-owned integrators, critical infrastructure owners and operators should also include geopolitical considerations in their risk assessments, such as how the critical infrastructure entity may be directly or indirectly targeted based on the geopolitical climate.

Critical infrastructure owners and operators should consider the following questions in their risk assessments to safeguard the security of their operational systems when working with third-party ICS integrators:

What organizational data does the integrator store or have access to?

Critical infrastructure network designs, device specifications, logs, and other data can all be useful information for malicious cyber actors. When evaluating the risk of enabling integrators to store or access this data, consider the potential for a malicious cyber actor to access this data through the integrator’s network.

Where is the data stored?

If the integrator is foreign-owned, consider whether the utility data is stored within the United States or internationally. If data is stored internationally, the laws of that respective country may govern it and may apply even if the integrator is a U.S. subsidiary.

Does the integrator have remote access for operational support?

If the integrator has remote access to the organization’s ICS network, then there is a potential risk that a malicious cyber actor could gain access to the integrator’s network and pivot into the utility’s network to gain control of their systems. Consider the security of the organization’s remote connections when evaluating the risk these potential access points pose to the organization’s network. 

Can the organization operate independently if the integrator is compromised?

Having redundancies in place and the ability to recover the system and operate without the integrator, especially for operationally critical processes, can reduce risk in the event of integrator compromise. Operators should maintain secure, offline backups of all software required to operate equipment to facilitate system recovery. 

Recommendations to Reduce Risk

The authoring agencies recommend critical infrastructure owners and operators implement the following steps to reduce the risks associated with using third-party ICS integrators:

• Include cybersecurity and supply chain cybersecurity in contracts and service agreements. When preparing service agreements, include requirements on areas such as:
  
  • Data storage locations, information protection agreements, and protection of ICS data and design documentation,
  • Remote access capabilities,
  • Basics of the integrator’s cybersecurity program,
  • Change management and patch management policies,
  • Actions taken to secure deployed components (e.g., changing default passwords, disabling unused ports),
  • Listing authorized personnel with access to systems, and
  • Processes that enable local engineering support when necessary, limiting required integrator intervention.
• Evaluate devices with external internet exposure. Organizations should work with integrators to understand where devices are hosted and minimize exposure by disconnecting devices from the public-facing internet.
• Monitor and log remote access. Ensure integrators access equipment using routes you are able to monitor. Use on-demand remote access if possible, so operators have to proactively allow remote access.
• Request an inventory of all software and hardware supplied by the integrator, as well as documentation for how it connects to your infrastructure and how it will be updated.
• Practice procedures and maintain capabilities for manual operations, keeping in mind, and accounting for, where third parties fit into the environment and recovery procedures.

Legal Notice and Terms of Use

CISA has added four new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.

• CVE-2026-85102 Check Point Multiple Products Improper Certificate Validation Vulnerability
• CVE-2026-93616 Check Point Multiple Products Path Traversal Vulnerability
• CVE-2026-93952 Arista VeloCloud Orchestrator Improper Input Validation Vulnerability
• CVE-2026-94127 F5 BIG-IP APM Heap-based Buffer Overflow Vulnerability

These types of vulnerabilities are a frequent attack vector 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.

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.
