CVE-2026-20223: Missing Authentication for Critical Function in Cisco Cisco Secure Workload
CVE-2026-20223 is a critical vulnerability in Cisco Secure Workload affecting multiple versions. It involves missing authentication on internal REST API endpoints, allowing unauthenticated remote attackers to access site resources with Site Admin privileges. Exploitation could lead to unauthorized reading of sensitive information and configuration changes across tenant boundaries. The vulnerability is due to insufficient validation and authentication of API requests. There is no confirmed patch or official remediation guidance available at this time. The vulnerability has a CVSS score of 10.0, indicating critical severity. No known exploits in the wild have been reported so far.
AI Analysis
Technical Summary
This vulnerability in Cisco Secure Workload arises from missing authentication checks on internal REST API endpoints. An attacker able to send crafted API requests to these endpoints can gain Site Admin privileges without authentication. This allows unauthorized access to sensitive data and the ability to modify configurations across tenant boundaries. The issue affects numerous versions of Cisco Secure Workload. The CVSS 3.1 vector indicates network attack vector, no privileges required, no user interaction, and complete confidentiality, integrity, and availability impact. No patch or official fix has been documented in the provided data.
Potential Impact
Successful exploitation grants an unauthenticated remote attacker Site Admin privileges, enabling them to read sensitive information and make configuration changes across tenant boundaries. This can severely compromise confidentiality, integrity, and availability of the affected Cisco Secure Workload deployments.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to Cisco Secure Workload management interfaces and internal APIs to trusted networks and authenticated users only. Monitor for unusual API activity and consider implementing network-level controls to limit exposure.
