Description Michael Kaplan 2021-04-21 15:41:02 UTC

Config File Provider Plugin 3.7.0 and earlier does not correctly perform permission checks in several HTTP endpoints.

This allows attackers with global Job/Configure permission to enumerate system-scoped credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.
