8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
An issue was discovered in the FileImporter extension in MediaWiki through 1.36. For certain relaxed configurations of the $wgFileImporterRequiredRight variable, it might not validate all appropriate user rights, thus allowing a user with insufficient rights to perform operations (specifically file uploads) that they should not be allowed to perform.
