Improper dependency pinning


The application does not make explicit the whole dependency tree it requires (direct and indirect third-party libraries) and their respective version.


  • Accept a range of versions can cause a version of a dependency that is not supported by the application to be automatically installed.
  • Install a dependency containing a known vulnerability and being unaware of it.
  • Use a dependency version that is not compatible with the application.


All dependencies must be declared with a specific version and must be referenced with a dependency manager (npm, pip, maven). This allows to standardize the projects construction and packaging.


Anonymous attacker with access to the application.
