Bundler-Audit is a Software Composition Analysis (SCA) tool designed specifically for Ruby applications. It scans theGemfile and Gemfile.lockto identify all declared dependencies and their resolved versions. The Gemfile specifies which gems the application depends on, while the Gemfile.lock ensures consistent dependency versions across environments. Bundler-Audit compares this dependency information against a database ofknown vulnerabilitiesto identify insecure or outdated gems. It does not rely on the Travis CI configuration file for vulnerability detection, nor does it compare against unknown vulnerabilities. Integrating Bundler-Audit into the Build and Test stage ensures that vulnerable third-party libraries are detected early, allowing developers to remediate issues before the application progresses further in the pipeline. This practice supports shift-left security and reduces the risk of introducing known vulnerabilities into production systems.
