phpMyFAQ is an open source FAQ web application. Versions 4.0.16 and below allow an authenticated user without the dlattachment permission to download FAQ attachments due to a incomprehensive permissions check. The presence of a right key is improperly validated as proof of authorization in attachment.php. Additionally, the group and user permission logic contains a flawed conditional expression that may allow unauthorized access. This issue has been fixed in version

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
