The module doesn't sufficiently protect certain routes from CSRF attacks. This vulnerability is mitigated by the fact that a site admin would have to perform further steps after the attack for it to have any effect. Solution:  Install the latest version: * If you use the Search API Solr module for Drupal 8+, upgrade to Search API Solr 4.3.10. [3] We also recommend checking your Solr configuration for any unintended changes.
