CISA Adds Three Known Exploited Vulnerabilities to Catalog
CISA has added three actively exploited vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog: CVE-2021-22054 (Omnissa Workspace ONE SSRF),...
Executive Summary
CISA has added three actively exploited vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog: CVE-2021-22054 (Omnissa Workspace ONE SSRF), CVE-2025-26399 (SolarWinds Web Help Desk Deserialization), and CVE-2026-1603 (Ivanti Endpoint Manager Authentication Bypass). These vulnerabilities affect critical enterprise software widely used in federal networks. Under BOD 22-01, FCEB agencies must remediate these CVEs by specified deadlines. The deserialization and authentication bypass flaws are particularly dangerous as they could enable remote code execution and unauthorized system access. CISA strongly recommends all organizations prioritize timely remediation of KEV Catalog vulnerabilities regardless of federal mandates. Organizations using affected products should immediately apply available patches and implement compensating controls to reduce exposure to active cyber threats.
Summary
CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2021-22054 Omnissa Workspace ONE Server-Side Request Forgery CVE-2025-26399 SolarWinds Web Help Desk Deserialization of Untrusted Data Vulnerability CVE-2026-1603 Ivanti Endpoint Manager (EPM) Authentication Bypass 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) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria .
