How CVE-2025-4416 Works
The CVE-2025-4416 vulnerability in Drupal’s Events Log Track module arises due to unrestricted resource allocation during event logging. Attackers can exploit this flaw by sending excessive event-tracking requests, overwhelming server memory and CPU. The module fails to implement throttling or limits, allowing malicious users to trigger denial-of-service (DoS) conditions. Affected versions include 0.0.0 to 3.1.10 and 4.0.0 to 4.0.1. The lack of input validation enables continuous resource exhaustion, crashing the system.
