Description
Cloud Foundry UAA, versions later than 4.6.0 and prior to 4.19.0 except 4.10.1 and 4.7.5 and uaa-release versions later than v48 and prior to v60 except v55.1 and v52.9, does not validate redirect URL values on a form parameter used for internal UAA redirects on the login page, allowing open redirects. A remote attacker can craft a malicious link that, when clicked, will redirect users to arbitrary websites after a successful login attempt.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.cloudfoundry.identity:cloudfoundry-identity-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.cloudfoundry.identity:cloudfoundry-identity-server to 4.7.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-11041 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.
