Users needing this SQL functionality are forced to upgrade to Solr 9.1. If Solr 8.11.3 is released, then it will be an option as well. Simply replacing Calcite and other JAR files may mostly work but could fail depending on the particulars of the query. Users interested in this or in patching their own versions of Solr should examine SOLR-16421 for a source patch.
Counter-Strike Source V63 Update
Description: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.
Description:The affected versions are vulnerable to a Remote Code Execution through theVelocityResponseWriter. A Velocity template can be provided throughVelocity templates in a configset velocity/ directory or as a parameter.A user defined configset could contain renderable, potentially malicious,templates. Parameter provided templates are disabled by default, but canbe enabled by setting params.resource.loader.enabled by defining aresponse writer with that setting set to true. Defining a responsewriter requires configuration API access.
Description:The DataImportHandler, an optional but popular module to pull in data fromdatabases and other sources, has a feature in which the whole DIHconfiguration can come from a request's "dataConfig" parameter. The debugmode of the DIH admin screen uses this to allow convenient debugging /development of a DIH config. Since a DIH config can contain scripts, thisparameter is a security risk. Starting with version 8.2.0 of Solr, use ofthis parameter requires setting the Java System propertyenable.dih.dataConfigParam to true.
