## Overview

When migrating a repository from another Gitea instance, Gitea used the page size reported in the source server's API settings to end its paginated downloads. A source that reported `max_response_items` as `0` made these loops run indefinitely and grow server memory until it was exhausted. Any user who can migrate repositories could point a migration at a server they control and cause a denial of service.

## Affected

- `gitea < 28.1.0`

## Remediation

Upgrade past the affected range:

- `gitea 28.1.0`
