Summary

Spring Security OAuth2 Authorization Server: Authorization endpoint performs insufficient validation of the request_uri parameter

Details

Spring Security Authorization Server's authorization endpoint performs insufficient validation of the request_uri parameter. An attacker can craft a malicious authorization request containing an invalid request_uri and an arbitrary, unvalidated redirect_uri, which can lead to an Open Redirect vulnerability.

Affected versions: Spring Security 7.0.0 through 7.0.5. Spring Authorization Server 1.5.0 through 1.5.7.

Severity

6.1 (Medium)
