Podamibe Appointment Calendar Security & Risk Analysis

The "podamibe-appointment-calendar" plugin v1.1.6 exhibits several concerning security practices, despite having no recorded historical vulnerabilities. The static analysis reveals a significant attack surface with 3 out of 4 entry points lacking authentication checks. This is particularly worrisome as 100% of the detected SQL queries are not using prepared statements, making them highly susceptible to SQL injection attacks if an unauthenticated user can trigger them. Furthermore, the presence of a taint flow with unsanitized paths, flagged as high severity, indicates a potential for arbitrary code execution or data compromise. The low percentage of properly escaped output (23%) also suggests a risk of Cross-Site Scripting (XSS) vulnerabilities. While the plugin has no known CVEs, the identified weaknesses in authentication, input sanitization, and output escaping create a substantial risk profile. The absence of capability checks on entry points further amplifies these risks.
