iPages – FlipBook Image & PDF Viewer Security & Risk Analysis

The "ipages-flipbook" v1.5.5 plugin exhibits a mixed security posture. On the positive side, it demonstrates good practices with a low attack surface, no known unpatched CVEs, and strong adherence to using prepared statements for SQL queries and proper output escaping. The presence of numerous nonce and capability checks also suggests an awareness of common WordPress security measures. However, the static analysis revealed significant concerns. The presence of the `unserialize` function is a known risk, particularly if the data being unserialized is not strictly controlled or sanitized, which can lead to Remote Code Execution vulnerabilities. While taint analysis didn't flag critical issues, the two flows with unsanitized paths warrant attention, even if they didn't reach a critical severity in this analysis.

The vulnerability history of this plugin is a significant red flag. With four known CVEs, including one high and three medium severity vulnerabilities, it indicates a pattern of past security weaknesses. The common types of past vulnerabilities like Missing Authorization, SQL Injection, and Cross-site Scripting suggest recurring issues with input validation and access control. While there are currently no unpatched vulnerabilities, the history suggests a need for continued vigilance and thorough security reviews of future updates. Overall, while the plugin has adopted some good security practices, the inherent risk from `unserialize` and the concerning vulnerability history necessitate careful consideration and monitoring.
