## Affected

- openobserve: through 0.16.1

## Description

OpenObserve is a cloud-native observability platform. In versions up to and including 0.16.1, when creating or renaming an organization with HTML in the name, the markup is rendered inside the invitation email. This indicates that user-controlled input is inserted into the email template without proper HTML escaping. As of time of publication, no patched versions are available.
