  1. Excludes community websites
  2. Includes IDORs that bypass authentication or authorization for significant actions
  3. Significant actions only, such as changing email/passwords, deleting accounts, etc.
  4. Must be able to conduct significant action (i.e., not defacement, phishing, cookie injection, etc.)
  5. For *.mozilla.org, *.mozilla.com, *.mozilla.net, and *.firefox.com.
  6. Lack of clickjacking protection (XFO, CSP) is insufficient to claim a bounty

Any bounty that receives a payout also obtains inclusion on our Hall of Fame.

Exclusions

Although we still appreciate being notified about them, the following issues fall outside the scope of our bug bounty program:

  • Self-XSS
  • Executing scripts on sandboxed domains (such as bmoattachments or mozillademos)
  • CSRF for non-significant actions (logout, etc.)
  • Clickjacking attacks without a documented series of clicks that produce a vulnerability
  • Spam (including issues related to SPF/DKIM/DMARC)
  • Denial-of-service attacks or issues related to rate limiting
  • Attacks that require social engineering (phishing)
  • Content injection, such as reflected text or HTML tags
  • Missing HTTP headers, except as where their absence fails to mitigate an existing attack
  • Authentication bypasses that require access to software/hardware tokens
  • Vulnerabilities that only affect users with specific browsers (must work either in Firefox or Chrome)
  • Vulnerabilities that require access to passwords, tokens, or the local system (e.g. session fixation)
  • Assumed vulnerabilities based upon version numbers only
  • Source code disclosures, as most of our code is open source
  • Vulnerabilities discovered shortly after their public release
  • Outdated TLS configurations which remain to support downloads from Windows XP systems
