In addition, Xinclude functionality provided in these config files is also affected in a similar way. The vulnerability can be used as XXE using file/ftp/http protocols in order to read arbitrary local files from the Solr server or the internal network. The manipulated files can be uploaded as configsets using Solr's API, allowing to exploit that vulnerability.","published":"2018-07-05T14:29:00.000Z","lastModified":"2026-06-17T02:04:07.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.0","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-611"],"affected":["apache/solr","netapp/snapcenter","netapp/storage automation store"],"epss":{"score":0.09025,"percentile":0.95252,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.0295,"percentile":0.86508},{"date":"2026-09-22","score":0.09025,"percentile":0.95042}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (9.03%).
