+Security is very important to us. If discover any issue regarding security, please disclose
+the information responsibly by sending an email to security (at) wekan.team and not by
+creating a GitHub issue. We will respond swiftly to fix verifiable security issues.
+
+We thank you with a place at our hall of fame page, that is
+at https://wekan.github.io/hall-of-fame . Others have just posted public GitHub issue,
+so they are not at that hall-of-fame page.

+## How should reports be formatted?

+
+## Who can participate in the program
+
+Anyone who reports a unique security issue in scope and does not disclose it to
+a third party before we have patched and updated may be upon their approval
+added to the Wekan Hall of Fame.
+
+## Which domains are in scope?
+
+No any public domains, because all those are donated to Wekan Open Source project,
+and we don't have any permissions to do security scans on those donated servers.
+
+Please don't perform research that could impact other users. Secondly, please keep
+the reports short and succinct. If we fail to understand the logics of your bug, we will tell you.
+
+You can [Install Wekan](https://github.com/wekan/wekan/releases) to your own computer
+and scan it's vulnerabilities there.
+
+## About Wekan versions
+
+There is only 2 versions of Wekan: Standalone Wekan, and Sandstorm Wekan.
+
+### Standalone Wekan Security
+
+Standalone Wekan includes all non-Sandstorm platforms. Some Standalone Wekan platforms
+like Snap and Docker have their own specific sandboxing etc features.
+
+Standalone Wekan by default does not load any files from Internet, like fonts, CSS, etc.
+This also means all Standalone Wekan functionality works in offline local networks.
+Wekan is used by companies that have [thousands of users](https://github.com/wekan/wekan/wiki/AWS) and at healthcare.
+
+Wekan uses xss package for input fields like cards, as you can see from
+[package.json](https://github.com/wekan/wekan/blob/devel/package.json). Other used versions can be seen from
+[Meteor versions file](https://github.com/wekan/wekan/blob/devel/.meteor/versions).
+Forms can include markdown links, html, image tags etc like you see at https://wekan.github.io .
+It's possible to add attachments to cards, and markdown/html links to files.
+
+Wekan attachments are not accessible without logging in. Import from Trello works by copying
+Trello export JSON to Wekan Trello import page, and in Trello JSON file there is direct links to all publicly
+accessible Trello attachment files, that Standalone Wekan downloads directly to Wekan MongoDB database in
+[CollectionFS](https://github.com/wekan/wekan/pull/875) format. When Wekan board is exported in
+Wekan JSON format, all board attachments are included in Wekan JSON file as base64 encoded text.
+That Wekan JSON format file can be imported to Sandstorm Wekan with all the attachments, when we get
+latest Wekan version working on Sandstorm, only couple of bugs are left before that. In Sandstorm it's not
+possible yet to import from Trello with attachments, because Wekan does not implement Sandstorm-compatible
+access to outside of Wekan grain.
+
+Standalone Wekan only has password auth currently, there is work in progress to add
+[oauth2](https://github.com/wekan/wekan/pull/1578), [Openid](https://github.com/wekan/wekan/issues/538),
+[LDAP](https://github.com/wekan/wekan/issues/119) etc. If you need more login security for Standalone Wekan now,
+it's possible add additional [Google Auth proxybouncer](https://github.com/wekan/wekan/wiki/Let's-Encrypt-and-Google-Auth) in front of password auth, and then use Google Authenticator for Google Auth. Standalone Wekan does have [brute force protection with eluck:accounts-lockout and browser-policy clickjacking protection](https://github.com/wekan/wekan/blob/devel/CHANGELOG.md#v080-2018-04-04-wekan-release). You can also optionally use some [WAF](https://en.wikipedia.org/wiki/Web_application_firewall)
+like for example [AWS WAF](https://aws.amazon.com/waf/).
+
+[All Wekan Platforms](https://github.com/wekan/wekan/wiki/Platforms)
+
+### Sandstorm Wekan Security
+
+On Sandstorm platform using environment variable Standalone Wekan features like Admin Panel etc are
+turned off, because Sandstorm platform provides SSO for all apps running on Sandstorm. 
+
+[Sandstorm](https://sandstorm.io) is separate Open Source platform that has been
+[security audited](https://sandstorm.io/news/2017-03-02-security-review) and found bugs fixed.
+Sandstorm also has passwordless login, LDAP, SAML, Google etc auth options already.
+At Sandstorm code is read-only and signed by app maintainers, only grain content can be modified.
+Wekan at Sandstorm runs in sandboxed grain, it does not have access elsewhere without user-visible
+PowerBox request or opening randomly-generated API key URL.
+Also read [Sandstorm Security Practices](https://docs.sandstorm.io/en/latest/using/security-practices/) and
+[Sandstorm Security non-events](https://docs.sandstorm.io/en/latest/using/security-non-events/).
+For Sandstorm specific security issues you can contact [kentonv](https://github.com/kentonv) by email. 
+
+## What Wekan bugs are eligible?
+
+Any typical web security bugs. If any of the previously mentioned is somehow problematic and
+a security issue, we'd like to know about it, and also how to fix it:
+
+- Cross-site Scripting
+- Open redirect
+- Cross-site request forgery
+- File inclusion
+- Authentication bypass
+- Server-side code execution
+
+## What Wekan bugs are NOT eligible?
+
+Typical already known or "no impact" bugs such as:
+
+- Brute force password guessign. Currently there is
+  [brute force protection with eluck:accounts-lockout](https://github.com/wekan/wekan/blob/devel/CHANGELOG.md#v080-2018-04-04-wekan-release).
+- Security issues related to that Wekan uses Meteor 1.6.0.1 related packages, and upgrading to newer
+  Meteor 1.6.1 is complicated process that requires lots of changes to many dependency packages.
+  Upgrading [has been tried many times, spending a lot of time](https://github.com/meteor/meteor/issues/9609)
+  but there still is issues. Helping with package upgrades is very welcome.
+- [Wekan API old tokens not replaced correctly](https://github.com/wekan/wekan/issues/1437)
+- Missing Cookie flags on non-session cookies or 3rd party cookies
+- Logout CSRF
+- Social engineering
+- Denial of service
+- SSL BEAST/CRIME/etc. Wekan does not have SSL built-in, it uses Caddy/Nginx/Apache etc at front.
+  Integrated Caddy support is updated often.
+- Email spoofing, SPF, DMARC & DKIM. Wekan does not include email server.
+
+Wekan is Open Source with MIT license, and free to use also for commercial use.
+We welcome all fixes to improve security by email to security (at) wekan.team .
