How to fix?

Upgrade org.apache.solr:solr-core to version 8.11.4, 9.7.0 or higher.

Overview

org.apache.solr:solr-core is an open source enterprise search platform built on Apache Lucene

Affected versions of this package are vulnerable to Improper Authentication due to insecure code in PKIAuthenticationPlugin and HttpSolrCall classes.

An attacker can bypass the authentication process by appending a fake ending to the URL path, which appears to be an unprotected API path but is internally stripped off after authentication and before API routing.

Note:

Solr instances using the PKIAuthenticationPlugin, which is enabled by default when Solr Authentication is used, are vulnerable.
