CISA Adds Four Known Exploited Vulnerabilities to Catalog ↗ source

July 21, 2026 CISA Alert

Summary

CVE-2021-27137 DD-WRT Stack-Based Buffer Overflow Vulnerability CVE-2026-0770 Langflow Inclusion of Functionality from Untrusted Control Sphere Vulnerability CVE-2026-63030 WordPress Core Interpretation Conflict Vulnerability CVE-2026-60137 WordPress Core SQL Injection Vulnerability These types of vulnerabilities are frequent attack vectors 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.
