Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

An issue was discovered in these Pivotal Cloud Foundry products: all versions prior to cf-release v270, UAA v3.x prior to v3.20.2, and UAA bosh v30.x versions prior to v30.8 and all other versions prior to v45.0. A cross-site scripting (XSS) attack is possible in the clientId parameter of a request to the UAA OpenID Connect check session iframe endpoint used for single logout session management.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    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.

  2. Fix

    Update org.cloudfoundry.identity:cloudfoundry-identity-server to 3.20.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-1190 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
