Static Analysis Summary

Here you can find the overall conclusion based on the various metadata and gathered information during the work of Stan on this project.

  • Project health: 100%

    This number was calculated based on the total number of used inspections and the number of triggered inspections in the project. The calculated number also defines the overall project health status.
  • The project is healthy

    Excellent work! Stan haven't found any vulnerabilities in the code.
  • Congratulations! Your project has zero vulnerabilities!

    Stan carefully run all configured inspection and found 0 observations and vulnerabilities to the project.

Observations

Based on the analysis results, Stan found different vulnerabilities distributed among the analysed files. In Stan terminology, we call such vulnerability as Observation. Below you can see the more detailed information about each observation, and find the possible ways to fix them for your project.

Configurations

This section describes the final Stan configuration that was used on the project and explains how this result was assembled. Stan runtime settings have many parts, and each of them can come from different configuration sources. Stan is using Environment variables, TOML configuration file and CLI arguments to get the final results. If some option is specified through the multiple sources, the most prioritized one is used.
