| Description | 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. |
