Description
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.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework.security:spring-security-oauth2-authorization-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.springframework.security:spring-security-oauth2-authorization-server to 7.0.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4r8w-73jc-3m7q is resolved across your whole dependency graph.
Workarounds
Stop reflecting attacker-controlled destinations: resolve every redirect target against an allowlist of paths or hosts you own, prefer a server-side key over a full URL in the request, and reject absolute URLs entirely where the flow only ever needs a relative one.
