SCA: security update for github.com/ory/fosite (GHSA-grfp-q2mm-hfp6)

medium Tenable Self-Hosted Container Security Plugin ID 431907

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - ORY Fosite is a security first OAuth2 & OpenID Connect framework for Go. In Fosite before version 0.34.1,
 the OAuth 2.0 Client's registered redirect URLs and the redirect URL provided at the OAuth2 Authorization
 Endpoint where compared using strings.ToLower while they should have been compared with a simple string
 match. This allows an attacker to register a client with allowed redirect URL
 https://example.com/callback. Then perform an OAuth2 flow and requesting redirect URL
 https://example.com/CALLBACK. Instead of an error (invalid redirect URL), the browser is redirected to
 https://example.com/CALLBACK with a potentially successful OAuth2 response, depending on the state of the
 overall OAuth2 flow (the user might still deny the request for example). This vulnerability has been
 patched in ORY Fosite v0.34.1. (CVE-2020-15234)
