CVE-2026-103506：Grafana SSO 設定授權繞過漏洞
CVE-2026-103506 - SSO settings authorization bypass
Grafana 在其 OSS 與 Enterprise 13.2 版本中，若啟用實驗性 kubernetesSsoSettingsApi 功能，已授權使用者可讀取 SSO 客戶端金鑰並修改全域 SSO 設定，造成授權繞過。
此漏洞可讓受信任使用者竊取SSO金鑰，提示需立刻停用實驗功能並加強許可權控制。
An authenticated user in Grafana can read SSO client secrets and modify instance-wide SSO settings without the required permissions (missing authorization). This affects Grafana OSS and Enterprise 13.2 installations with the experimental kubernetesSsoSettingsApi feature toggle enabled, which is disabled by default.
