CVE-2026-33376

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...

CVE-2026-33376

CVE-2026-33376 affects Grafana’s Auth Proxy IPv6 allow-list: by default it accepts /32 addresses. Addresses with explicit masks are not affected. The practical impact is a potentially unintended bypass of access controls for the Auth Proxy component only; other components (Okta, SAML, LDAP) are u...
