Summary IBM Event Processing is vulnerable to an Authorization Bypass due to the use of a Next.js component. Since Next.js can be used in the UI layer or API routing, unauthorized users may gain access to protected resources or functionalities, potentially compromising the system's integrity. Vulnerability Details CVEID:CVE-2025-29927 DESCRIPTION: Next.js is a React framework for building full-stack web applications. Starting in version 1.11.4 and prior to versions 12.3.5, 13.5.9, 14.2.25, and 15.2.3, it is possible to bypass authorization checks within a Next.js application, if the authorization check occurs in middleware. If patching to a safe version is infeasible, it is recommend that you prevent external user requests which contain the x-middleware-subrequest header from reaching your Next.js application. This vulnerability is fixed in 12.3.5, 13.5.9, 14.2.25, and 15.2.3.
