grafana: When using an IPv6 allow-list for the Auth Proxy feature, it defaults to /32 addresses
CVE-2026-33376 is fixed in 2 products on 1 platform, first by OPENSUSE-SU-2026:20940-1, released June 10, 2026. It is not reported as exploited. Patch Radar priority: High.
When using an IPv6 allow-list for the Auth Proxy feature, it defaults to /32 addresses. Addresses specifying a mask explicitly are not affected; to mitigate easily, add the desired mask (usually /128) to the addresses. Only auth proxy is affected; Okta, SAML, LDAP, etc are unaffected here.
