WP Project Manager – Task, team, and project management plugin featuring kanban board and gantt charts <= 2.6.16 - Authenticated (Subscriber+) SQL Injection

The WP Project Manager – Task, team, and project management plugin featuring kanban board and gantt charts plugin for WordPress is vulnerable to SQL Injection via the 'project_id' parameter of the /wp-json/pm/v2/projects/2/task-lists REST API endpoint in all versions up to, and including, 2.6.16 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, who have been granted access to a project, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
