CISA Adds One Known Exploited Vulnerability to Catalog
Overview
The Cybersecurity and Infrastructure Security Agency (CISA) has added a new vulnerability, identified as CVE-2026-64849, to its Known Exploited Vulnerabilities (KEV) Catalog. This vulnerability affects the MLflow platform and allows for server-side request forgery (SSRF), which attackers can exploit to gain unauthorized access to sensitive systems. The addition to the catalog indicates that there is active exploitation of this vulnerability, posing significant risks, particularly to federal agencies. As part of its guidelines, CISA emphasizes the need for rapid remediation of such high-risk vulnerabilities. While the directive primarily targets federal agencies, CISA encourages all organizations to prioritize addressing vulnerabilities listed in the KEV Catalog to safeguard their systems effectively.
Key Takeaways
- Active Exploitation: This vulnerability is being actively exploited by attackers. Immediate action is recommended.
- Affected Systems: MLflow platform, federal agencies, organizations using MLflow
- Action Required: Organizations are advised to apply patches or updates for MLflow as soon as they become available.
- Timeline: Newly disclosed
Original Article Summary
CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2026-64849 MLflow Server-Side Request Forgery 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.
