CISA Adds Seven Known Exploited Vulnerabilities to Catalog

All CISA Advisories

September 2, 2026 at 12:00 PM

Actively Exploited

Overview

CISA has recently added seven new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, indicating that these flaws are currently being actively exploited by cybercriminals. The vulnerabilities include SQL Injection in Sangoma Switchvox (CVE-2026-9586), HTTP Request/Response Smuggling in Kludex Starlette (CVE-2026-48710), and OS Command Injection in Kestra OSS (CVE-2026-49869), among others. These vulnerabilities pose significant risks, particularly to federal agencies, as they could allow attackers to gain full control of affected systems. CISA's Binding Operational Directive 26-04 urges federal agencies to prioritize the rapid remediation of these high-risk vulnerabilities, but CISA also encourages all organizations to adopt a similar risk-based approach. Organizations are advised to monitor the KEV Catalog for updates and to submit any known exploited vulnerabilities not currently listed for consideration.

Key Takeaways

Active Exploitation: This vulnerability is being actively exploited by attackers. Immediate action is recommended.
Affected Systems: Sangoma Switchvox, Kludex Starlette, Kestra OSS, BerriAI LiteLLM, JFrog Artifactory, SonicWall SMA1000 Appliances
Action Required: Federal agencies should prioritize patching these vulnerabilities on publicly exposed assets.
Timeline: Newly disclosed

Original Article Summary

CISA has added seven new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2026-9586 Sangoma Switchvox SQL Injection Vulnerability CVE-2026-48710 Kludex Starlette HTTP Request/Response Smuggling Vulnerability CVE-2026-49869 Kestra OSS OS Command Injection Vulnerability CVE-2026-59822 BerriAI LiteLLM Improper Authentication Vulnerability CVE-2026-82329 JFrog Artifactory Improper Authentication Vulnerability CVE-2026-83548 SonicWall SMA1000 Appliances Server-Side Request Forgery Vulnerability CVE-2026-83549 SonicWall SMA1000 Appliances OS Command Injection 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.
