CVE-2026-22022: Apache Solr Unauthorized Bypass Of Certain "predefined Vulnerability
HIGHCVE-2026-22022 is a HIGH (CVSS 8.2) unauthorized bypass of certain "predefined vulnerability (CWE-285: Improper Authorization) affecting Apache Solr libraries in the Maven ecosystem. The issue involves unauthorized bypass of certain "predefined permission" rules in the rulebasedauthorizationplugin. Remediation is available by upgrading affected packages to version 9.10.1.
CVE-2026-22022 at a Glance
Security Impact
CVSS: 8.2
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N).
How to Fix CVE-2026-22022
To remediate this vulnerability, upgrade all affected Apache Solr dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.solr</groupId>
<artifactId>solr-core</artifactId>
<version>9.10.1</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.solrHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-22022, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.solrAnalyze the terminal output to locate any version of Apache Solr in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.10.1), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.solr command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

"details" : "Deployments of Apache Solr 5.3.0 through 9.10.0 that rely on Solr's \"Rule Based Authorization Plugin\" are vulnerable to allowing unauthorized access to certain Solr APIs, due to insufficiently strict input validation in those components. Only deployments that meet all of the following criteria are impacted by this vulnerability:\n\n * Use of Solr's \"RuleBasedAuthorizationPlugin\"\n * A RuleBasedAuthorizationPlugin config (see security.json) that specifies multiple \"roles\"\n * A RuleBasedAuthorizationPlugin permission list (see security.json) that uses one or more of the following pre-defined permission rules: \"config-read\", \"config-edit\", \"schema-read\", \"metrics-read\", or \"security-read\".\n * A RuleBasedAuthorizationPlugin permission list that doesn't define the \"all\" pre-defined permission\n * A networking setup that allows clients to make unfiltered network requests to Solr. (i.e. user-submitted HTTP/HTTPS requests reach Solr as-is, unmodified or restricted by any intervening proxy or gateway)\n\nUsers can mitigate this vulnerability by ensuring that their RuleBasedAuthorizationPlugin configuration specifies the \"all\" pre-defined permission and associates the permission with an \"admin\" or other privileged role. Users can also upgrade to a Solr version outside of the impacted range, such as the recently released Solr 9.10.1.",
