I am sure there is a clear security risks of using online tools like
1. JsonFormatter
2. YAML validator
3. SQL formatter
4. Image converter
5. PDF converter
many more...<p>I am looking for real world examples/cases of security vulnerability/issues you/your company encountered.
This helps me to make a case at my company to implement a company wide deployment of these tools(open source) as internal tools for developers to use.
