Description

Weblate is a web based localization tool. From version 5.15 to before version 2026.6, Weblate&#39;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.
