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.

Momentum Bonus, the more you submit, the more you earn!

  • There is a 7-day sliding window where you can build momentum on your rewards for the Upwork program, going forward, submissions made within the 7-day sliding window will be sorted by the severity assigned and the momentum bonus will be applied from highest to lowest severity, for example if you submit 3 bugs in this sequence [P3, P2, P1] within a 7 day sliding window, the submissions will be sorted by severity [P1, P2, P3] and the first (Bug with P1 Severity) pays 100%, the second (Bug with P2 Severity) pays 110%, the third (Bug with P3 Severity) pays 120%, etc. This scales to a maximum payout amount of 200% (double reward) the original value.
