CVE-2026-44847— MaxKB 访问控制错误漏洞

MaxKB: Webhook Trigger Authentication Bypass

MaxKB is an open-source AI assistant for enterprise. Prior to 2.9.0, MaxKB's webhook trigger endpoint (/api/trigger/v1/webhook/{trigger_id}) is accessible without authentication. The WebhookAuth class unconditionally returns (None, {}), which Django REST Framework interprets as successful authentication. Combined with optional per-trigger token verification and no backend enforcement of token requirements, any unauthenticated attacker who knows a valid trigger ID can invoke webhook triggers to execute their bound tasks. This vulnerability is fixed in 2.9.0.

认证机制不恰当

MaxKB 访问控制错误漏洞

MaxKB是1Panel-dev开源的一款基于大语言模型和 RAG 的开源知识库问答系统。 MaxKB 2.9.0之前版本存在访问控制错误漏洞，该漏洞源于Webhook触发端点/api/trigger/v1/webhook/{trigger_id}无需身份验证即可访问，WebhookAuth类无条件返回(None, {})，导致任何知道有效触发ID的未认证攻击者均可调用Webhook触发器执行绑定任务。
