How we Disclose Security Issues

** The following section only applies to security issues found in released versions. Issues that concern the master development branch only will be fixed immediately on the branch with the corresponding PR containing the description of the nature and severity of the issue. **

Patches for identified security issues are applied to all affected versions and new minor versions are released. At the same time we release a statement at the Nominatim blog describing the nature of the incident. Announcements will also be published at the geocoding mailinglist.
