CVE-2026-41654
Full vulnerability record from the local CVENow database.
Description
Weblate is a web based localization tool. Prior to version 5.17.1, 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). This issue has been patched in version 5.17.1.

"value": "Weblate es una herramienta de localización basada en web. Antes de la versión 5.17.1, un usuario autenticado con permiso project.add (por defecto en Weblate SaaS alojado y para cualquier usuario con un plan de facturación/prueba activo) puede importar un ZIP de copia de seguridad de proyecto manipulado cuyo components/[name].json contiene una URL de repositorio elegida por el atacante que apunta a una dirección privada (por ejemplo, http://127.0.0.1:9999/) o que utiliza un esquema no permitido (por ejemplo, file: //, git://). Weblate persiste el componente a través de Component.objects.bulk_create([component])[0], lo que omite el full_clean() de Django y por lo tanto nunca ejecuta el validador validate_repo_url. La URL se escribe posteriormente textualmente en .git/config por configure_repo(pull=False). Este problema ha sido parcheado en la versión 5.17.1."
