# Security Policy
[Security](https://nextcloud.com/security/) is very important to us.
If you believe you have found a security vulnerability that meets our definition of a security
vulnerability, please report is as described below.
## Context
Please review our [threat model and accepted risks](https://nextcloud.com/security/threat-model) to learn what
is currently considered a security vulnerability versus expected behavior. And review what is considered
[in scope or bounty eligible](https://hackerone.com/nextcloud/policy_scopes).
## Reporting a Vulnerability
** **Please do _not_ report security vulnerabilities through public GitHub issues.** **
If you have discovered a security matter with Nextcloud, please read our
[responsible disclosure guidelines](https://nextcloud.com/security/) and contact us at
[hackerone.com/nextcloud](https://hackerone.com/nextcloud).
Your report should include:
- Product version
- A vulnerability description
- Reproduction steps
- Any other details you think are likely to be important
### What to Expect
You should receive an initial acknowledgement within 24 hours in most cases.
A member of the security team will confirm the vulnerability, determine its impact, follow-up with any questions,
and coordinate the fix and publication.
The fix will be applied to all applicable and still supported stable branches, tested, and packaged in the next security release.
The vulnerability will be publicly announced after the release. Finally, your name will be added
to the [hall of fame](https://hackerone.com/nextcloud/thanks) as a thank you from the entire Nextcloud
community.
If the vulnerability involves an app that is not maintained by Nextcloud (i.e. hosted by the
Nextcloud project but community maintained, or hosted elsewhere), the security team will try to coordinate with the
current maintainer and help to get the issue fixed in similar fashion.
### Bug Bounties
If you are reporting for a bug bounty, more complete reports can contribute to a higher bounty award. Details
on past bounty ranges can be found at [hackerone.com/nextcloud](https://hackerone.com/nextcloud).
