CVE-2026-50127
PUBLISHED
CVSS 5.9 MEDIUM
Reported by GitHub_M · Published June 10, 2026
Weblate is a web based localization tool. 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.
