CVE-2026-53576— kestra-io kestra 授权问题漏洞

Kestra: Unauthenticated RCE via /configs path-suffix auth-filter bypass

Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.45 and 1.3.21, the authentication filter for the REST API (@Filter("/api/v1/**")) treats any request whose path ends in /configs as the public instance-config endpoint and forwards it without a credential check. kestra addresses its resources by URL path segments that the caller chooses (/api/v1/{tenant}/flows/{namespace}, /api/v1/{tenant}/executions/{namespace}/{id}, /api/v1/{tenant}/namespaces/{namespace}/kv/{key}). An anonymous caller picks the literal configs as the final segment, and the request bypasses Basic-Auth entirely. Because the bypass reaches the flow-create and execution-trigger routes, an unauthenticated caller creates a flow containing a Shell or Process task and runs it. The task executes as root inside the kestra container. The official docker-compose.yml mounts /var/run/docker.sock, so root in the container reaches the host Docker daemon. This vulnerability is fixed in 1.0.45 and 1.3.21.

kestra-io kestra 授权问题漏洞

kestra是Kestra公司开源的一个工作流自动化平台。 kestra-io kestra存在安全漏洞，该漏洞源于 REST API 的认证过滤器将路径以 /configs 结尾的请求视为公开实例配置端点并绕过凭证检查，导致未经身份验证的攻击者可创建包含 Shell 或 Process 任务的流程并以 root 身份在容器内执行，进而通过挂载的 Docker 套接字访问主机 Docker 守护进程。
