The software fails to enforce role-based access controls for certain Gateway API invocations. Users with the 'Internal/Everyone' role can invoke these APIs, bypassing intended permission checks. This same vulnerability also affects Internal Service APIs, potentially exposing them in WSO2 APIM 3.x versions. A malicious actor with a valid user account on a vulnerable deployment can perform sensitive operations against the Gateway REST API regardless of their actual roles or privileges. This could lead to unintended behavior or misuse, particularly in production environments.

In Webhook API invocations, the component accepts user-supplied input for HTTP request headers without sufficient validation or sanitization, allowing these headers to be injected into HTTP responses. By exploiting this vulnerability, a malicious actor can inject or overwrite arbitrary HTTP response headers. This can lead to various adverse effects, including the manipulation of browser caching, alteration of security-related headers, and the injection of sensitive information such as cookie values, potentially enabling session hijacking or other malicious activities.
