SCA: security update for fastapi-opa (GHSA-5f5c-8rvc-j8wf)
medium Tenable Cloud Security Plugin ID 410789
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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. (CVE-2024-40627)
