CVE-2026-33376
When using an IPv6 allow-list for the Auth Proxy feature, it defaults to /32 addresses.
Impact
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.
