CAPI (Cloud Controller) versions prior to 1.101.0 are vulnerable to a denial-of-service attack in which an unauthenticated malicious attacker can send specially-crafted YAML files to certain endpoints, causing the YAML parser to consume excessive CPU and RAM.

Cloud Foundry CAPI (Cloud Controller) versions prior to 1.98.0 allow authenticated users having only the "cloud_controller.read" scope, but no roles in any spaces, to list all droplets in all spaces (whereas they should see none).

Cloud Foundry Routing (Gorouter) versions prior to 0.206.0 allow a malicious developer with "cf push" access to cause denial-of-service to the CF cluster by pushing an app that returns specially crafted HTTP responses that crash the Gorouters.

Cloud Foundry CAPI (Cloud Controller), versions prior to 1.97.0, when used in a deployment where an app domain is also the system domain (which is true in the default CF Deployment manifest), were vulnerable to developers maliciously or accidentally claiming certain sensitive routes, potentially resulting in the developer's app handling some requests that were expected to go to certain system components.

Cloud Foundry Routing (Gorouter), versions prior to 0.204.0, when used in a deployment with NGINX reverse proxies in front of the Gorouters, is potentially vulnerable to denial-of-service attacks in which an unauthenticated malicious attacker can send specially-crafted HTTP requests that may cause the Gorouters to be dropped from the NGINX backend pool.

Go before 1.13.13 and 1.14.x before 1.14.5 has a data race in some net/http servers, as demonstrated by the httputil.ReverseProxy Handler, because it reads a request body and writes a response at the same time.

In Cloud Foundry UAA, versions prior to 74.14.0, a CSRF vulnerability exists due to the OAuth2 state parameter not being checked in the callback function when authenticating with external identity providers.

Cloud Foundry Cloud Controller (CAPI), versions prior to 1.91.0, logs properties of background jobs when they are run, which may include sensitive information such as credentials if provided to the job. A malicious user with access to those logs may gain unauthorized access to resources protected by such credentials.

Cloud Foundry CredHub, versions prior to 2.5.10, connects to a MySQL database without TLS even when configured to use TLS. A malicious user with access to the network between CredHub and its MySQL database may eavesdrop on database connections and thereby gain unauthorized access to CredHub and other components.

Cloud Foundry Cloud Controller API (CAPI), version 1.88.0, allows space developers to list all global service brokers, including service broker URLs and GUIDs, which should only be accessible to admins.
