    CVE-2024-40627 (GCVE-0-2024-40627)

    Vulnerability from cvelistv5 – Published: 2024-07-15 19:21 – Updated: 2024-08-02 04:33
    VLAI
    Title
    OpaMiddleware does not filter HTTP OPTIONS requests
    Summary
    Fastapi OPA is an opensource fastapi middleware which includes auth flow. HTTP `OPTIONS` requests are always allowed by `OpaMiddleware`, even when they lack authentication, and are passed through directly to the application. `OpaMiddleware` allows all HTTP `OPTIONS` requests without evaluating it against any policy. If an application provides different responses to HTTP `OPTIONS` requests based on an entity existing (such as to indicate whether an entity is writable on a system level), an unauthenticated attacker could discover which entities exist within an application. This issue has been addressed in release version 2.0.1. All users are advised to upgrade. There are no known workarounds for this vulnerability.
