From version 5.15 to before version 2026.6, Weblate's VCS_RESTRICT_PRIVATE did not properly account for some transitional IPv6 ranges, multicast addresses, or some semi-private IPv4 ranges, which allowed some addresses to bypass private range restrictions. This issue has been patched in version 2026.6."

Desde la versión 5.15 hasta antes de la versión 2026.6, el VCS_RESTRICT_PRIVATE de Weblate no tuvo en cuenta correctamente algunos rangos de IPv6 transicionales, direcciones de multidifusión o algunos rangos de IPv4 semiprivados, lo que permitió que algunas direcciones eludieran las restricciones de rango privado. Este problema ha sido parcheado en la versión 2026.6."
