Deeper analysis

CVE-2024-11135 is a SQL injection vulnerability in the Eventer plugin for WordPress, affecting all versions up to and including 3.9.8. The issue arises in the 'eventer_get_attendees' function due to insufficient escaping of the user-supplied 'event' parameter and lack of sufficient preparation in the existing SQL query, allowing attackers to append additional SQL queries.

Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no user interaction required. Successful exploitation enables extraction of sensitive information from the database. The vulnerability has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and is associated with CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).
