**Name of the Vulnerable Software and Affected Versions** Apache Solr versions prior to 5.3.1 **Description** A cross-site scripting (XSS) issue exists, allowing remote attackers to inject arbitrary web script or HTML. This is achieved via the `entry` parameter to a `plugins/cache` URI in the stats page of the Admin UI. **Recommendations** For versions prior to 5.3.1, update to version 5.3.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the `plugins/cache` URI in the Admin UI to minimize the risk of exploitation. Avoid using the `entry` parameter in the affected URI until the issue is resolved.
