Vulnerability
Details
CVE-2026-20223 is a critical vulnerability in Cisco Secure Workload’s internal REST API access validation. The root cause is insufficient validation and authentication controls on REST API endpoints, allowing unauthenticated remote attackers to bypass access controls [1].
Exploitation
Scenario
An attacker can exploit this flaw by sending specially crafted API requests to an affected endpoint without any authentication [1]. The exploitation requires network access to the affected system but no prior credentials or user interaction. Cisco notes that this vulnerability affects both SaaS and on-premise deployments of the Cisco Secure Workload Cluster Software [1].
Impact
Successful exploitation grants the attacker privileges equivalent to the Site Admin role. This allows reading sensitive information and making configuration changes across tenant boundaries, severely compromising the confidentiality and integrity of the affected system [1].
Mitigation
Cisco has released software updates to address this vulnerability. There are no workarounds available. Users should patch their systems as soon as possible to mitigate risk [1].
