Summary
Frappe ERPNext before 15.110.0 and 16.x before 16.21.0 contains an SQL injection flaw in some endpoints. The application does not validate input in these endpoints, so it passes crafted values into database queries (CWE-89). An authenticated attacker can send specially crafted requests to manipulate database queries and extract sensitive information from the database.
