CVE-2023-2636Public exploitNetwork attack vector

Database-result disclosure via unsanitized course id

Published Jul 17, 2023 · Updated Feb 13, 2025

SQL injection in Aori Nevo GradeBook 5.0.1 and earlier allows remote authenticated users to alter database queries via the course id. The WordPress admin-ajax course action inserts the id parameter into an SQL statement without adequate sanitization or escaping. Subscriber-level access is sufficient, and the published UNION payload demonstrates database-result disclosure rather than proving arbitrary writes or service interruption.
