Duzz Portal – Stripe Custom Customer Payments Security & Risk Analysis

The duzz-custom-portal plugin v1.2.2 exhibits a generally good security posture, with robust application of nonce and capability checks, and a high percentage of properly escaped output. The absence of any recorded historical vulnerabilities further strengthens this impression. However, a significant concern arises from the static analysis of SQL queries, where 100% of queries are not using prepared statements. This presents a notable risk for SQL injection vulnerabilities, especially if any of the input parameters used in these queries originate from user-controlled sources. While the taint analysis did not reveal critical or high-severity unsanitized flows, the presence of two flows with unsanitized paths warrants careful review to ensure these do not lead to exploitable weaknesses, particularly in conjunction with the un-prepared SQL queries.

Despite the strong adherence to WordPress security best practices in many areas, the unmitigated risk associated with raw SQL queries is the primary weakness. The plugin's history of zero vulnerabilities could indicate either a very well-written codebase historically or simply a lack of targeted discovery, making the identified code signals more critical. In conclusion, while the plugin demonstrates many positive security attributes, the lack of prepared statements for SQL queries introduces a significant potential for exploitation that needs immediate attention.
