CVE-2021-29262

7.5 highEPSS 6.7%

High (7.5) in apache solr. EPSS 6.7% chance of exploitation in the next 30 days. Fixed in org.apache.solr:solr-core 8.8.2.

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.
