CVE-2026-50127
Last modified
CVE-2026-50127 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. 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. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
