CVE-2026-33376 (GCVE-0-2026-33376)

Vulnerability from cvelistv5 – Published: 2026-05-13 19:28 – Updated: 2026-08-27 17:22

Title

Auth Proxy IPv6 whitelist bypass

Summary

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.

Summary

Red Hat Security Advisory: Multicluster Global Hub 1.5.6 security update

Severity

Important

Scope

14 vulnerabilities in this advisory, including CVE-2026-33376.

CVE-2026-33376

A flaw in Grafana's Auth Proxy IPv6 allow-list incorrectly defaults to a broad /32 subnet mask instead of a strict /128. This misconfiguration allows remote attackers to bypass access restrictions, potentially leading to unauthorized access and data manipulation.

7.4 (High)
