Risk Assessment

The schema-markup-customizer plugin v1.5 exhibits a generally good security posture based on the provided static analysis. The absence of identified dangerous functions, raw SQL queries, file operations, and external HTTP requests are strong indicators of secure coding practices. Furthermore, the 100% usage of prepared statements for SQL queries and the proper handling of 80% of output escaping are commendable.
