GOVERNMENT CYBERSECURITY AGENCY DIRECTIVES

Sovereign Directives, KEV Catalog & Technical Alerts

1 Government Directive
Government & Agency Invariance Standard: The directives below represent formal alerts, binding operational directives (BOD), and Known Exploited Vulnerabilities (KEV) determinations issued by sovereign cybersecurity authorities (CISA, UK NCSC, FBI, BSI, CCCS). They provide statutory mandates and ground-truth technical confirmation of active in-the-wild exploitation.

CISA Adds One Known Exploited Vulnerability to Catalog

Publication Date 2026-10-23
Primary Authority CISA Cybersecurity Advisories
Assurance Tier Sovereign Agency Ground Truth
CVE-2026-114625
Technical Findings & Forensic Guidance:

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2026-114625 Arista VeloCloud Orchestrator SQL Injection 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.
