CVE-2023-51293

What is CVE-2023-51293?

The PHPJabbers Event Booking Calendar version 4.0 contains a vulnerability due to a lack of rate limiting in its 'Forgot Password' and 'Email Settings' features. This vulnerability enables attackers to exploit the system by sending an excessive number of emails on behalf of legitimate users, potentially leading to a Denial of Service (DoS) situation. Such activity can overwhelm the server, disrupt the service, and hinder user access, emphasizing the need for effective rate limiting mechanisms to safeguard against abuse.
