Streamline looks forward to working with the security community to find vulnerabilities in order to keep our businesses and customers safe.
You can report vulnerabilities in this form.
Our primary focus is on high/critical findings right now, and we aim to expand scope beyond that over time.
We’ll try to keep you informed about our progress throughout the process.
Our focus is on unauthorized access to our production database or admin panel. Logic bugs that allow an attacker to bypass limits on free accounts and get access to premium features are not eligible for a bounty.
We are not interested in small or medium bugs at the moment.
For critical findings, you can expect a reward up to $100 or less.
To promote the discovery and reporting of vulnerabilities and increase user safety, we ask that you:
Share the security issue with us in detail;
Please be respectful of our existing applications. Spamming forms through automated vulnerability scanners will not result in any bounty or award since those are explicitly out of scope;
Give us a reasonable time to respond to the issue before making any information about it public and work with us on making reports public.
Do not access or modify our data or our users’ data, without explicit permission of the owner. Only interact with your own accounts or test accounts for security research purposes.
Contact us immediately if you do inadvertently encounter user data. Do not view, alter, save, store, transfer, or otherwise access the data, and immediately purge any local information upon reporting the vulnerability to Streamline.
Act in good faith to avoid privacy violations, destruction of data, and interruption or degradation of our services (including denial of service).
Otherwise comply with all applicable laws.
Please provide detailed reports with reproducible steps. If the report is not detailed enough to reproduce the issue, the issue may not be marked as triaged.
Submit one vulnerability per report, unless you need to chain vulnerabilities to provide impact. This can be done in this form.
When duplicates occur, we only triage the first report that was received (provided that it can be fully reproduced).
Multiple vulnerabilities caused by one underlying issue will be treated as one valid report.
Social engineering (e.g. phishing, vishing, smishing) is prohibited.
Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service. Only interact with accounts you own or with explicit permission of the account holder.
Out of scope vulnerabilities
We generally recommend also reading up on industry best practices from the Google Bug Hunter university and Dropbox's guidelines. Please consider (1) attack scenario / exploitability, and (2) security impact of the bug. The following issues are considered out of scope:
Clickjacking on pages with no sensitive actions
Cross-Site Request Forgery (CSRF) on unauthenticated forms or forms with no sensitive actions
Attacks requiring MITM or physical access to a user's device. Only exception is that if you invalidate a token or cookie by pressing logout or disabling the app in the UI, then the cookie or token should stop working.
Previously known vulnerable libraries without a working Proof of Concept.
Comma Separated Values (CSV) injection without demonstrating a vulnerability.
Missing best practices (e.g., SSL/TLS configuration or SMTP/Email configuration).
Any activity that could lead to the disruption of our service (DoS) via consumption of resources due to multiple requests.
Content spoofing and text injection issues without showing an attack vector/without being able to modify HTML/CSS
Rate limiting or bruteforce issues on non-authentication endpoints
Missing best practices in Content Security Policy.
Missing HttpOnly or Secure flags on cookies
Missing email best practices (Invalid, incomplete or missing SPF/DKIM/DMARC records, etc.)
Vulnerabilities only affecting users of outdated or unpatched browsers [Less than 2 stable versions behind the latest released stable version]
Software version disclosure / Banner identification issues / Descriptive error messages or headers (e.g. stack traces, application or server errors).
Open redirect - unless an additional security impact can be demonstrated
Issues that require unlikely user interaction
Logic bugs that allow an attacker to bypass limits on free accounts and get access to some premium features
Search engines or other crawlers (like wayback machine) having a list of Streamline file links -- these are all shared publicly by our customers and we are aware of the risk this index has.
Any activities conducted in a manner consistent with this policy will be considered authorized conduct and we will not initiate legal action against you. If legal action is initiated by a third party against you in connection with activities conducted under this policy, we will take steps to make it known that your actions were conducted in compliance with this policy.
Thank you for helping keep Streamline and our users safe!
