CISA Adds Six Known Exploited Vulnerabilities to Catalog (2025.05.19) CISA has added six new vulnerabilities to itsKnown Exploited Vulnerabilities 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 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 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 ofCatalog vulnerabilitiesas part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet thespecified criteria.

Update to How CISA Shares Cyber-Related Alerts and Notifications (2025.05.12) Update May 13: In an effort to enhance user experience and highlight the most timely and actionable information for cyber defenders, CISA announced a shift in how we share cybersecurity alerts and advisories. We recognize this has caused some confusion in the cyber community. As such, we have paused immediate changes while we re-assess the best approach to sharing with our stakeholders.
Starting May 12, CISA is changing how we announce cybersecurity updates and the release of new guidance. These announcements will only be shared through CISA social media platforms and email and will no longer be listed on our Cybersecurity Alerts & Advisories webpage. The focus of our Cybersecurity Alerts & Advisories webpage will now be on urgent information tied to emerging threats or major cyber activity. CISA wants this critical information to get the attention it deserves and ensure it is easier to find. Well continue to communicate releases and updates to our stakeholders. To stay informed, subscribe to receive our email notifications on CISA.gov. You can also follow us on X @CISACyber for timely cybersecurity updates. Note: If youve previously used RSS feeds to track Known Exploited Vulnerabilities Catalog updates, please subscribe to the KEV subscription topic through GovDelivery to continue receiving notifications. We greatly appreciate stakeholder feedback which played a part in this change and thank you for staying connected with CISA. CISA Releases Five Industrial Control Systems Advisories (2025.05.08) CISA released five Industrial Control Systems (ICS) advisories on May 8, 2025.
