Vulnerability Description
LogicalDOC Community Edition through 9.3 contains a missing authorization vulnerability in the zip-export servlet that allows authenticated users to export restricted folders by supplying a folderId parameter. Attackers can request /zip-export with a restricted folder ID, since ZipExport.addFolderDocuments() skips READ and DOWNLOAD permission checks, to download all of its documents in a ZIP archive.
