Details

As written in the advisory (Markdown source, shown as plain text).

### Impact An authenticated user with `project.add` permission (default on hosted Weblate SaaS and for any user holding an active billing/trial plan) can import a crafted project backup ZIP whose `components/<name>.json` contains an attacker-chosen `repo` URL pointing at a **private address** (e.g. `http://127.0.0.1:9999/`) or using a **non-allow-listed scheme** (e.g. `file://`, `git://`). Weblate persists the component via `Component.objects.bulk_create([component])[0]`, which bypasses Django's `full_clean()` and therefore never runs the `validate_repo_url` validator. The URL is subsequently written verbatim into `.git/config` by `configure_repo(pull=False)`. ### Patches * https://github.com/WeblateOrg/weblate/pull/19061 * https://github.com/WeblateOrg/weblate/pull/19062 ### Workarounds Limiting who can create projects limits the scope. ### Resources Weblate thanks @fg0x0 for reporting this vulnerability via GitHub.
