Description

Authentication Bypass in cf-auth-proxy in Cloud Foundry Foundation all installations allows an unauthenticated remote attacker to gain read access to every log and metric for every application and platform component via minting a JWT that the cf-auth-proxy accepts as a valid logs.admin token. Affected versions: - log-cache_release: all versions through v3.2.6 (inclusive); fixed in v3.2.7 or later - CF Deployment: all versions through v55.?.0 (inclusive); fixed in v55.?.0 or later (bundles log-cache_release v3.2.7)
