Description
Cloud Foundry Foundation UAA, versions 4.12.X and 4.13.X, introduced a feature which could allow privilege escalation across identity zones for clients performing offline validation. A zone administrator could configure their zone to issue tokens which impersonate another zone, granting up to admin privileges in the impersonated zone for clients performing offline token validation.

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 4.12.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-1262 is resolved across your whole dependency graph.
Workarounds
Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.
