Risk Assessment

The "smart-invoice-and-billing-management" plugin v1.2 presents a mixed security posture. On the positive side, there are no recorded vulnerabilities (CVEs) and the plugin demonstrates a low attack surface with no identified AJAX handlers, REST API routes, shortcodes, or cron events. However, significant concerns arise from the static analysis. A concerning 100% of output is unescaped, which is a major security weakness that could lead to cross-site scripting (XSS) vulnerabilities if any user-controlled data is ever displayed without proper sanitization. Additionally, while the plugin uses prepared statements for 38% of its SQL queries, the remaining 62% are likely to be vulnerable to SQL injection if not handled with extreme care.

Key Concerns

  • 0% output escaping
  • SQL queries not always prepared
  • No nonce checks
  • No capability checks
  • High severity taint flow found
