Title

Spring Authorization Server: Open Redirect via request_uri parameter

Summary

In versions of Spring Authorization Server 1.5.0 through 1.5.7, the authorization endpoint performs insufficient validation of the request_uri parameter. An attacker can craft a request containing an invalid request_uri paired with an unvalidated redirect_uri, which can result in an open redirect to an attacker-controlled site.

Severity

6.1 (Medium)
