CISA Adds Collabora Online OS Command Injection Vulnerability to Known Exploited Catalog

The Cybersecurity and Infrastructure Security Agency (CISA) has added CVE-2026-110447 to its Known Exploited Vulnerabilities (KEV) Catalog, citing evidence of active exploitation. The vulnerability affects Collabora Online's Built-in CODE Server and involves an OS command injection flaw. Successful exploitation could allow remote attackers to execute arbitrary commands on the affected system, potentially leading to total control of the asset.

Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. The directive reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by CVEs listed in the 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. Organizations aware of exploited vulnerabilities not currently listed in the KEV Catalog can submit them for potential addition through CISA's KEV Nomination Form.
