These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.
CISA encourages users and administrators to review newly released ICS advisories for technical details and mitigations. CISA Adds Five Known Exploited Vulnerabilities to Catalog (2025.10.20) CISA has added five new vulnerabilities to itsKnown Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.
These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilitiesestablished the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See theBOD 22-01 Fact Sheetfor more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation ofKEV Catalog vulnerabilitiesas part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet thespecified criteria. CISA Releases Thirteen Industrial Control Systems Advisories (2025.10.16) CISA released thirteen Industrial Control Systems (ICS) advisories on October 16, 2025. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.

CISA Directs Federal Agencies to Mitigate Vulnerabilities in F5 Devices (2025.10.15) Today, CISA issued Emergency Directive ED 26-01: Mitigate Vulnerabilities in F5 Devices to direct Federal Civilian Executive Branch agencies to inventory F5 BIG-IP products, evaluate if the networked management interfaces are accessible from the public internet, and apply newly released updates from F5. A nation-state affiliated cyber threat actor has compromised F5 systems and exfiltrated data, including portions of the BIG-IP proprietary source code and vulnerability information, which provides the actor with a technical advantage to exploit F5 devices and software. This poses an imminent threat to federal networks using F5 devices and software. Key Actions Required:
For detailed guidance, refer to the full Emergency Directive ED 26-01. CISA Adds One Known Exploited Vulnerability to Catalog (2025.10.15) CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.
