Risk Assessment

The 'qr-code-adv' plugin version 1 exhibits a mixed security posture. On one hand, the plugin has a zero-known vulnerability history, suggesting a historical focus on security or a lack of discovered issues. The static analysis also shows no dangerous functions, no raw SQL queries, and no external HTTP requests, which are positive indicators. However, significant concerns arise from the code analysis. The plugin demonstrates a very low rate of proper output escaping (4%), indicating a high likelihood of cross-site scripting (XSS) vulnerabilities. Furthermore, all identified taint flows have unsanitized paths, raising immediate concerns about how user-supplied data is handled, even though no critical or high severity taint issues were explicitly flagged at this version. The absence of nonce checks and capability checks across all entry points is a major security gap, potentially allowing unauthorized actions or data manipulation if any entry points were to become exposed or if additional vulnerabilities are discovered.

Key Concerns

  • Low output escaping rate (4%)
  • Taint flows with unsanitized paths (2/2)
  • No nonce checks
  • No capability checks
