Low signal — verdict needed

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

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)

    This scores high on paper (CVSS 7.5) but the real-world signal is low. It is not in CISA KEV and no public exploit was found, and near-term exploitation looks unlikely. Verify your own exposure before treating it as urgent. It is reachable over the network with no authentication and no user interaction, which is the most dangerous profile. Not an emergency for most teams, but patch it in your normal cycle and check whether the affected component is actually exposed in your setup.
