Name of the Vulnerable Software and Affected Versions: Adminer version 4.8.1

Description: Adminer 4.8.1, when using Monolog for logging, is susceptible to a Denial of Service (memory consumption) through a crafted serialized payload, resulting in a PHP Object Injection issue. Remote, unauthenticated attackers can trigger this by sending a malicious serialized object, which forces excessive memory usage, rendering the Adminer interface unresponsive and potentially causing a server-level DoS. Multiple simultaneous requests can lead to a complete server crash requiring manual intervention.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
