Potential fix for https://github.com/rubyconfig/config/security/code-scanning/4
To fix the problem, replace
IO.readwithFile.read. TheFile.readmethod does not allow shell execution through inputs starting with|. This ensures the code remains secure against malicious inputs. The functionality of reading the file content is preserved with no change in behavior.The changes will be made in the file
spec/support/rails_helper.rb, specifically on line 8. The replacement ensures that the file content is read securely usingFile.read.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
