CVE-2025-14561Access Control Bypass via Publisher REST APIs in Multiple WSO2 Products Allows Cross-Tenant Operations
Critical 9.0
In plain English
A critical-severity improper access control in WSO2 API Control Plane from WSO2. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 36% of all known vulnerabilities).
Official description
In multi-tenant deployments, the Publisher REST APIs fail to enforce tenant isolation correctly. This allows a user in one tenant, possessing sufficient privileges to invoke these APIs, to perform operations that impact other tenants. The vulnerability allows a privileged user to perform publisher operations such as exposing or modifying API Metadata in another tenant environment. This impact is only realized in multi-tenant deployments.
