GHSA-j63h-hmgw-x4j7 Opencast still publishes global system account credentials

• Maven org.opencastproject:opencast-common: < 17.6 → fixed in 17.6 • Maven org.opencastproject:opencast-ingest-service-impl: < 17.6 → fixed in 17.6 • Maven org.opencastproject:opencast-kernel: < 17.6 → fixed in 17.6 • Maven org.opencastproject:opencast-publication-service-oaipmh-remote: < 17.6 → fixed in 17.6

Description Opencast prior to versions 17.6 would incorrectly send the hashed global system account credentials (ie: `org.opencastproject.security.digest.user` and `org.opencastproject.security.digest.pass`) when attempting to fetch mediapackage elements included in a mediapackage XML file. A previous CVE prevented many cases where the credentials were inappropriately sent, but not all. The remainder are addressed with this patch. Impact Anyone with ingest permissions could cause Opencast to send its hashed global system account credentials to a url of their choosing.
