9.1 criticalEPSS 4.7%

Critical (9.1) in apache solr. EPSS 4.7% chance of exploitation in the next 30 days. Fixed in org.apache.solr:solr-parent 8.8.2.

When using ConfigurableInternodeAuthHadoopPlugin for authentication, Apache Solr versions prior to 8.8.2 would forward/proxy distributed requests using server credentials instead of original client credentials. This would result in incorrect authorization resolution on the receiving hosts.
