# What CISOs need to know: CISA Adds Four Known Exploited Vulnerabilities to Catalog
What happened
CISA has added four new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation.
CVE-2026-15409 SonicWall SMA1000 Appliances Server-Side Request Forgery Vulnerability CVE-2026-15410 SonicWall SMA1000 Appliances Code Injection Vulnerability CVE-2026-56155 Microsoft Active Directory Federation Services Insufficient Granularity of Access Control Vulnerability CVE-2026-56164 Microsoft SharePoint Server Missing Authentication for Critical Function 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.

Why it matters
This signal sits squarely in the 24-framework compliance coverage (NIS2 / SOC 2 / ISO 27001 / HIPAA / PCI DSS) territory. CISOs and compliance leads at mid-market EU/US organisations should map it to their control set within the next 7-14 days.
What to do this week
1. Read the source advisory in full and identify whether your environment is in scope. 2. Check existing controls against the requirement / vulnerability. 3. Document evidence of remediation or non-applicability - auditors will ask.
