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 Vulnerabilities established the Known Exploited Vulnerabilities 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 the BOD 22-01 Fact Sheet for 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 of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria. CISA Releases Three Industrial Control Systems Advisories (2025.04.29) CISA released three Industrial Control Systems (ICS) advisories on April 29, 2025. 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 Three Known Exploited Vulnerabilities to Catalog (2025.04.28) CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

CISA Releases Seven Industrial Control Systems Advisories (2025.04.24) CISA released seven Industrial Control Systems (ICS) advisories on April 24, 2025. 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 Releases Five Industrial Control Systems Advisories (2025.04.22) CISA released five Industrial Control Systems (ICS) advisories on April 22, 2025. 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 Releases Six Industrial Control Systems Advisories (2025.04.17) CISA released six Industrial Control Systems (ICS) advisories on April 17, 2025. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.

CISA Releases Guidance on Credential Risks Associated with Potential Legacy Oracle Cloud Compromise (2025.04.16) CISA is aware of public reporting regarding potential unauthorized access to a legacy Oracle cloud environment. While the scope and impact remains unconfirmed, the nature of the reported activity presents potential risk to organizations and individuals, particularly where credential material may be exposed, reused across separate, unaffiliated systems, or embedded (i.e., hardcoded into scripts, applications, infrastructure templates, or automation tools). When credential material is embedded, it is difficult to discover and can enable long-term unauthorized access if exposed. The compromise of credential material, including usernames, emails, passwords, authentication tokens, and encryption keys, can pose significant risk to enterprise environments. Threat actors routinely harvest and weaponize such credentials to:
CISA recommends the following actions to reduce the risks associated with potential credential compromise:
