Sources and claim methodology

Upstream source description

Weblate is a web-based continuous localization platform used to manage software translations. In versions prior to 2026.7, the REST API did not properly enforce the scope of project- and workspace-scoped teams, allowing a user to submit invalid team configurations through the API. By assigning projects to a team via these unvalidated requests, a user could grant access to projects they were not authorized to see or manage. This could expose private projects and permit translation, repository, and project-management operations outside the user's intended permission scope. This issue is fixed in version 2026.7.
