CF CLI version prior to v6.45.0 (bosh release version 1.16.0) writes the client id and secret to its config file when the user authenticates with --client-credentials flag. A local authenticated malicious user with access to the CF CLI config file can act as that client, who is the owner of the leaked credentials.

Cloud Foundry Log Cache, versions prior to 1.1.1, logs its UAA client secret on startup as part of its envstruct report. A remote attacker who has gained access to the Log Cache VM can read this secret, gaining all privileges held by the Log Cache UAA client. In the worst case, if this client is an admin, the attacker would gain complete control over the Foundation.
