CVE-2026-22022 (opens in a new tab)How to fix?
Upgrade org.apache.solr:solr-core to version 9.10.1 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 Missing Authorization in the Rule Based Authorization Plugin, by which the getPermissionName() function can be forced to return null. An attacker can gain unauthorized access to some APIs if the following conditions are met:
- The deployment uses the
RuleBasedAuthorizationPlugin - Multiple "roles" are specified in the plugin config
- The plugin's permission list includes any of the predefined permission rules "config-read", "config-edit", "schema-read", "metrics-read", "security-read"
- The permission list does not define the "all" permission
- Untrusted HTTP/HTTPS requests are accepted without checking and filtering the methods in use.
Workaround
This vulnerability can be avoided by configuring the RuleBasedAuthorizationPlugin to use the "all" pre-defined permission, and associating it with an "admin" or other privileged role.
