⚠️ By participating in this program, you agree to:

πŸ§‘β€πŸ« Discussing and disclosing vulnerabilities
We know that some researchers who find really interesting bugs would like to discuss them or share them with others, like:

  • Presenting findings at security conferences
  • Writing blog posts about discoveries
  • Creating videos that present proof-of-concepts
  • Discussing findings in social media platforms, like Reddit

We kindly ask that you don't discuss or disclose the details of bugs you have reported to us though without our consent. We need time to fix the bugs! πŸ§‘β€πŸ”§

Once the bug is fixed and confirmed to no longer be vulnerable, we're happy to collaborate on safely presenting discoveries to the wider security community 🀝.
