Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (7.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

When starting Apache Solr versions prior to 8.8.2, configured with the SaslZkACLProvider or VMParamsAllAndReadonlyDigestZkACLProvider and no existing security.json znode, if the optional read-only user is configured then Solr would not treat that node as a sensitive path and would allow it to be readable. Additionally, with any ZkACLProvider, if the security.json is already present, Solr will not automatically update the ACLs.
