CVE-2022-26630Network attack vector

Authenticated arbitrary file upload

Published Apr 5, 2022 · Updated Aug 3, 2024

Arbitrary file upload in Jellycms 3.8.1 and earlier allows remote authenticated users to place attacker-chosen files via db.php. The public CVE record identifies app/admin/Controllers/db.php as the affected locus but does not disclose which upload operation accepts the file or what validation it omits. A valid low-privilege account is required, and public evidence does not establish whether uploaded content is executable or externally reachable.
