Here at NodeBB, we pride ourselves on producing high-quality and secure code, and we regularly put that to the test by utilising our own software1. However, no code is 100% perfect, and there are some vulnerabilities and bugs that could critically impact running instances of NodeBB.
As of November 2017, we've launched a bug bounty program to supplement our efforts to find these vulnerabilities and to reward those who submit them to us for fixing. Security vulnerabilities can be reported to the NodeBB team by emailing firstname.lastname@example.org.
We take every issue seriously, and aim to triage and deploy a fix as soon as possible.
Our mean time for a first response is: < 1 day.
Our mean time for a committed fix is: 2-3 days.
We will award bounties for verified and qualified vulnerabilities as follows:
- Medium ($128)
- CSRF / exploit that causes a user to perform an operation they didn't explicitly consent to
- Exposure of private user data or content (e.g. exposure of private posts or user email/IP address, etc.)
- High — XSS exploits ($256)
- Critical — exploit resulting in privilege escalation to admin, or downloading the site database ($512+)
Notes and Limitations
- Report all bugs to email@example.com. Posts to our forum or emailed directly to someone at the NodeBB team may result in delays.
- Please test and report against our testbed instance: https://try.nodebb.org . It runs the latest released NodeBB code, and is updated one day after the latest release.
- We reserve the right to reject a vulnerability report if it has been reported by someone else before you.
- Social engineering attacks and physical attacks are not covered under the bug bounty umbrella
- Only the core code and bundled plugins qualify for the bug bounty. Third-party plugins are not covered. The following modules are considered "bundled":
We'll do our best to prioritise security issues over any other issues at NodeBB, so we would kindly ask you to hold off on disclosure until a time is agreed-upon (typically 30-90 days).
1 Actually, it'd be a little sad if we didn't, wouldn't it?
