CVE-2026-20223: Missing Authentication for Critical Function in Cisco Cisco Secure Workload
A vulnerability in the access validation of internal REST APIs of Cisco Secure Workload could allow an unauthenticated, remote attacker to access site resources with the privileges of the Site Admin role. This vulnerability is due to insufficient validation and authentication when accessing REST API endpoints. An attacker could exploit this vulnerability if they are able to send a crafted API request to an affected endpoint. A successful exploit could allow the attacker to read sensitive information and make configuration changes across tenant boundaries with the privileges of the Site Admin user.
AI Analysis
Technical Summary
This vulnerability in Cisco Secure Workload is due to missing authentication checks on internal REST API endpoints. An unauthenticated attacker can send crafted API requests to gain Site Admin privileges, enabling access to sensitive data and configuration changes across tenant boundaries. The issue affects many versions of Cisco Secure Workload and is rated critical with a CVSS 3.1 score of 10.0. The vulnerability is caused by insufficient validation and authentication mechanisms in the REST API access control. No official patch or remediation level has been provided yet, and no known exploits have been reported.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to gain Site Admin privileges, leading to full read and write access to site resources, sensitive information disclosure, and configuration changes across tenant boundaries. This compromises confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the Cisco vendor advisory for current remediation guidance. Since no official fix or temporary workaround is currently documented, organizations should monitor Cisco advisories closely and restrict access to the affected Cisco Secure Workload management interfaces until a patch is available.
