Security at Linear
At Linear, we care deeply about the safety and security of our customer’s data. This is why we greatly value any inputs from our community that can help us detect vulnerabilities in our product.
If you have discovered an issue that is not part of our out-of-scope vulnerabilities, please send an email to email@example.com with the following details:
- A summary of the issue and potential impact
- A breakdown of the steps to replicate the issue
- Details of the environment you are using
- If available, any proof-of-concept code to exploit the vulnerability
Upon receiving your email, our team will start investigating the issue. We will keep you updated on the progress and may reach back for further details if needed. Once the issue is resolved we will update our customers.
Of course, we want to compensate your effort, so for any valid vulnerabilities with a CVSS score of 4 or higher, we will reach back to you with a financial reward.
