Miggo AIRoot Cause Analysis

The vulnerability stems from an unauthenticated HTTP endpoint exposing credential IDs. Jenkins plugins typically implement web endpoints via methods in controller classes annotated with @WebMethod. The advisory specifically calls out credential ID enumeration via an endpoint, which would map to a doListCredentials or similar method in the configuration class handling Xray-Jira integration. The function would appear in runtime profiling when unauthorized users access the credential enumeration endpoint.
