[TLP:CLEAR] Apache Solr warns of 1 vulnerability
The Apache Software Foundation warns of a vulnerability in Apache Solr. The fix will be included in the not yet released versions 9.11.0 and 10.1.0. Until they are released, it is recommended as a temporary measure to remove the template users (superadmin, admin, search and index) from the security.json file, or to change their passwords [1].
An unauthenticated remote attacker can gain full administrative access to the Apache Solr cluster due to hard-coded credentials in the Basic Authentication setup tool (bin/solr auth enable) [1].

- Apache Solr; >=9.4.0, <=9.10.1, =10.0.0
