Upwork For this program, we're inviting researchers to test our freelancer platform and mobile iOS/Android/Desktop apps. Our goal with this program is to ensure that our customers are using a secure platform that's free of security vulnerabilities. Please note: Upwork regularly releases new code, updates will be posted in the announcement section highlighting new code. This is a great opportunity for Upwork and the researcher community to work together to find vulnerabilities! Watch for new releases on Upwork's Blog.
