# Repository security advisories
The actions you can take in a repository security advisory depend on whether you have admin or write permissions to the security advisory.
## Permissions overview
Repository owners, organization owners, security managers, and users with the **admin** role can:
* Create a security advisory for the repository.
* Access all security advisories for the repository.
* Add collaborators to the security advisory.
Collaborators have **write** permissions to the security advisory.
| Action | Write permissions | Admin permissions |

### Permission differences for global security advisories
Unlike repository security advisories, anyone can contribute to **global security advisories** in the GitHub Advisory Database at [github.com/advisories](https://github.com/advisories). Edits to global advisories will not change or affect how the advisory appears on the repository. See [Editing security advisories in the GitHub Advisory Database](/en/code-security/how-tos/report-and-fix-vulnerabilities/fix-reported-vulnerabilities/edit-advisory-database).
