Risk Assessment

The 'flippingbook' plugin v2.0.2 exhibits a generally positive security posture with strong practices in output escaping and a lack of dangerous functions or file operations. The plugin also demonstrates capability checks for its code paths, which is a good security control. However, a significant concern arises from the use of raw SQL queries without prepared statements, indicating a potential for SQL injection vulnerabilities. While the static analysis did not reveal any direct taint flows, the raw SQL usage is a clear risk that should not be overlooked. The plugin has a history of one known medium severity Cross-Site Scripting (XSS) vulnerability, although it is currently patched. This history, combined with the identified raw SQL, suggests a need for continued vigilance and code review to ensure robust protection against common web application attacks.

Key Concerns

  • Raw SQL queries without prepared statements detected
  • History of medium severity Cross-Site Scripting (XSS) vulnerability
