CVE-2025-22216Network attack vector

Cross-zone account access via session reuse

Published Jan 31, 2025 · Updated Jan 31, 2025

Session isolation failure in Cloud Foundry UAA 77.20.1 and 77.21.0 through 77.24.0 allows remote authenticated users to access other zones. The session-validation path accepts a JSESSIONID established through a corporate identity provider without binding the stored session to the requested identity zone. Exploitation requires an authenticated corporate-IDP session, a multi-zone deployment, and browser interaction; successful reuse crosses zone boundaries with that user's session privileges.
