💥 Time to wrap up this year and kick-off the new year with a bang! We’re wrapping up the year with our End of Year Holiday Extravaganza, High-Risk Bonus Blitz Challenge, and Superhero Challenge for the Wordfence Bug Bounty Program.

Through January 6th, 2025, our program has an expanded scope for all researchers with a new lower active install count threshold, automatic bonuses for in-scope submissions, an extra bonus for those focusing on high-risk vulnerabilities, a minimum bounty for all submissions, increased pending report limits, and our rewards remain as high as $31,200.
