Security is a top priority at Piwik. As potential issues are discovered, we validate, patch and release fixes as quickly as we can.
We have a security bug bounty program in place that rewards researchers for finding security issues and disclosing them to us. We also document here how you can make your own Piwik data safer and secure your server.
Please subscribe to the Changelog to be notified of new releases (including security releases).
The Piwik Security Bug Bounty Program is designed to encourage security research in Piwik software and to reward those who help us create the safest web analytics platform.
The bounty for valid critical security bugs is a $500 (US) cash reward. The bounty for non-critical bugs is $200 (US), paid via Paypal.
Since we started this program in Jan 2011, we have already rewarded more than 15 researchers. This program has been very successful in improving code quality and fixing all known security issues in Piwik.
The bounty will be awarded for security bugs that meet the following criteria:
We also maintain a list of requests for security improvements.
Please email security issues to security@piwik.org. Please provide as much detail as you can about your environment, Piwik version, plugins used (if relevant), and any other relevant information.
You will receive a response from a team member acknowledging receipt of your email, typically within 24 hrs. If you do not receive a response, please do not assume we’re ignoring you – it’s quite possible your email didn’t make it through a spam filter.
We appreciate your patience and input. Some bugs take time to correct and the process may involve a review of the codebase for similar problems. Coordinating across time zones and work schedules can be time-consuming. Please do not disclose the vulnerability to anyone until a few days after the release of the stable Piwik, and after the advisory is issued.
You will be credited in the security announcement and in the Changelog. If applicable, the security bug bounty will be paid via Paypal. Thank you for making the free software world better.
Core developers are all committed to achieving the highest standard of security. All Piwik PHP code should adhere to the security checklist. All commits to the Piwik Git repository are reviewed by at least two core developers.
Regular external security reviews do take place, and some of these have contributed a few security suggestions. We have also conducted two paid security reviews from the top php security researchers.
We hope Piwik is not vulnerable to any critical security bugs, and we are committed to ensuring that this is the case. Thank you for your support!
