CVE-2025-14561
Access Control Bypass via Publisher REST APIs in Multiple WSO2 Products Allows Cross-Tenant Operations
Overview
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.

Solution
Enforce tenant isolation in Publisher REST APIs to prevent cross-tenant operations.
  • Review and enforce tenant isolation for all Publisher API calls.
  • Validate user permissions against the correct tenant context.
  • Implement strict access controls for cross-tenant operations.
  • Deploy updates addressing API tenant isolation flaws.
