Security Bounty Program

We are WHMCS, the complete web hosting automation solution

Security researchers play an important part in helping keep our product secure and so in an effort to reward those who discover and report issues to us in a responsible way, we offer monetary rewards.

How much do you pay for the discovery of security vulnerabilities?

Rewards range from $75.00 to $5,000.00 depending on the type and severity of the vulnerability being reported.

Rewards can be paid out via PayPal, BitCoin, or Western Union.

What qualifies as a vulnerability?

Any design or implementation issue within the WHMCS software that substantially affects the confidentiality or integrity of user data or the system.

Examples include:

What is out of Scope?

Note: Vulnerability reports submitted regarding third party applications are communicated to the proper party and WHMCS works with these parties to coordinate a fix wherever possible.
