CVE-2018-11041
MEDIUMCVE-2018-11041 is a medium-severity (CVSS 6.1) Open Redirect vulnerability in org.cloudfoundry.identity:cloudfoundry-identity-server. O3 Security confirms whether CVE-2018-11041 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
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.

Detection & mitigation playbook
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. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2018-11041 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2018-11041. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
