CISA Adds One Known Exploited Vulnerability to Catalog
CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. The vulnerability is a Server-Side Request Forgery (SSRF) vulnerability in MLflow.
Intelligence analysis by Llama
CISA has added a new vulnerability to its KEV Catalog due to evidence of active exploitation. The vulnerability is a Server-Side Request Forgery (SSRF) vulnerability in MLflow.
Imagine you're a hacker trying to break into a computer system. One way to do this is by tricking the system into making requests to a website that you control. This is called a Server-Side Request Forgery (SSRF) attack. CISA has added a new vulnerability to its list because hackers are already using this trick to break into systems. It's like a warning sign saying 'be careful, hackers are already using this trick'.

CVE-2026-64849: MLflow SSRF Vulnerability
CISA has added CVE-2026-64849 to its Known Exploited Vulnerabilities (KEV) Catalog due to evidence of active exploitation. This vulnerability is a Server-Side Request Forgery (SSRF) vulnerability in MLflow, which is a frequent attack vector for malicious cyber actors. SSRF vulnerabilities allow attackers to send requests from the server to an unintended location, potentially leading to unauthorized access or data breaches. This type of vulnerability poses significant risks to the federal enterprise and highlights the importance of prioritizing security updates based on risk.
Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk
BOD 26-04 establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. The directive 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.
CISA’s KEV Catalog and Risk-Based Vulnerability Management
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.
Key points
- CISA has added CVE-2026-64849 to its Known Exploited Vulnerabilities (KEV) Catalog due to evidence of active exploitation.
- The vulnerability is a Server-Side Request Forgery (SSRF) vulnerability in MLflow.
- BOD 26-04 requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities.
- CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities.
If organizations prioritize remediation of KEV Catalog vulnerabilities, they can reduce the risk of exploitation and protect their systems from malicious actors.
If organizations fail to prioritize remediation of KEV Catalog vulnerabilities, they may leave their systems open to exploitation, potentially leading to data breaches or unauthorized access.
