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...
