CVE-2020-5400Network attack vector

Credential disclosure via background-job property logging

Published Feb 27, 2020 · Updated Sep 17, 2024

Sensitive-data exposure in Cloud Foundry CAPI before 1.91.0 allows remote authenticated users with log access to obtain job credentials. The job runner writes complete background-job properties under the “about to run job” log message instead of filtering credential-bearing fields. Exposure requires a job carrying secrets and access to operator logs; affected examples include service-broker jobs and server-side app manifests.
