Adminer · Adminer · CVE-2025-43960
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.
