CVE-2024-2321Network attack vector

Protected API access via refresh-token misvalidation

Published Feb 27, 2025 · Updated Feb 27, 2025

Incorrect authorization in WSO2 API Manager and Identity Server allows remote attackers to access protected APIs with an admin refresh token. The API authorization path improperly maps a refresh token to protected resources and omits the expected access-token and session-cookie checks. A valid administrator refresh token is required; successful requests can read or alter API resources until the longer-lived token expires.
