In Cloud Foundry Foundation cf-release versions prior to v285; cf-deployment versions prior to v1.7; UAA 4.5.x versions prior to 4.5.5, 4.8.x versions prior to 4.8.3, and 4.7.x versions prior to 4.7.4; and UAA-release 45.7.x versions prior to 45.7, 52.7.x versions prior to 52.7, and 53.3.x versions prior to 53.3, the SessionID is logged in audit event logs. An attacker can use the SessionID to impersonate a logged-in user.

An issue was discovered in Cloud Foundry Foundation cf-release (all versions prior to v279) and UAA (30.x versions prior to 30.6, 45.x versions prior to 45.4, 52.x versions prior to 52.1). In some cases, the UAA allows an authenticated user for a particular client to revoke client tokens for other users on the same client. This occurs only if the client is using opaque tokens or JWT tokens validated using the check_token endpoint. A malicious actor could cause denial of service.
