CVE-2025-24814 is fixed in lucene-solr on 1 platform, first by DEBIAN-CVE-2025-24814, released January 27, 2025. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2025-24814 - Priority: Routine - CVSS: 5.5 (medium) - EPSS: 0.0122 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Jan 27, 2025 ## Description Core creation allows users to replace "trusted" configset files with arbitrary configuration Solr instances that (1) use the "FileSystemConfigSetService" component (the default in "standalone" or "user-managed" mode), and (2) are running without authentication and authorization are vulnerable to a sort of privilege escalation wherein individual "trusted" configset files can be ignored in favor of potentially-untrusted replacements available elsewhere on the filesystem.  These replacement config files are treated as "trusted" and can use "" tags to add to Solr's classpath, which an attacker might use to load malicious code as a searchComponent or other plugin. This issue affects all Apache Solr versions up through Solr 9.7.  Users can protect against the vulnerability by enabling authentication and authorization on their Solr clusters or switching to SolrCloud (and away from "FileSystemConfigSetService").  Users are also recommended to upgrade to Solr 9.8.0, which mitigates this issue by disabling use of "" tags by default. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | lucene-solr Debian 12.15 (bookworm) | 3.6.2+dfsg-23 | [DEBIAN-CVE-2025-24814](https://patchblox.com/security/data/fix/linux/debian-cve-2025-24814.md) | Jan 27, 2025 | | Linux | lucene-solr Debian 13.5 (trixie) | 3.6.2+dfsg-23 | [DEBIAN-CVE-2025-24814](https://patchblox.com/security/data/fix/linux/debian-cve-2025-24814.md) | Jan 27, 2025 | | Linux | lucene-solr Debian 14 | 3.6.2+dfsg-23 | [DEBIAN-CVE-2025-24814](https://patchblox.com/security/data/fix/linux/debian-cve-2025-24814.md) | Jan 27, 2025 | --- Data as of 2026-11-09T01:18:40Z UTC.
