Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Solr (org.apache.solr:solr-core, versions 8.6.0 through 9.10.0) is vulnerable in standalone mode when the allowPaths setting restricts file access. The create core API does not validate some parameters, so an attacker who can reach it can make Solr check and read file-system paths that allowPaths should block, and create cores from accessible configsets. On Windows systems that allow UNC paths, this can also disclose NTLM user hashes. Upgrade to version 9.10.1 or later. Until then, enable the RuleBasedAuthorizationPlugin and block untrusted users from the core-admin-edit permission.
