CVE-2026-85401Public exploitNetwork attack vector

Authenticated file access via missing permission check

Published Sep 4, 2026 · Updated Sep 4, 2026

Improper access control in Dolibarr ERP & CRM allows remote authenticated users to browse and write files through its Legacy File Manager. The connector's config.inc.php loads the application session but, in affected releases, fails to verify administrator or website-write rights before exposing media browsing and upload operations. Any signed-in account, including one with no module permissions, can view files in the exposed tree and create folders or upload files writable by the web server.
