How to fix?

Upgrade vrana/adminer to version 4.8.4 or higher.

Overview

vrana/adminer is a Database management in a single file.

Affected versions of this package are vulnerable to Resource Exhaustion via connecting to an attacker-controlled service that responds with HTTP redirects. An attacker can cause a denial of service by exploiting PHP configuration limits.

Notes:

  1. This is only exploitable if specific PHP configuration limits are set to allow excessive HTTP redirects.

  2. Adminer is no longer supported, but this issue was fixed in AdminerEvo
