CVE-2025-66490 (CNNVD-202512-1667)
中文标题:
Traefik 安全漏洞
英文标题:
Traefik doesn't Prevent Path Normalization Bypass in Router + Middleware Rules
漏洞描述
中文描述:
Traefik是Traefik开源的一款开源的反向代理与负载均衡工具。 Traefik 2.11.31版本至3.6.2版本存在安全漏洞，该漏洞源于路径规范化绕过，可能导致请求绕过安全控制。
英文描述:
Traefik is an HTTP reverse proxy and load balancer. For versions prior to 2.11.32 and 2.11.31 through 3.6.2, requests using PathPrefix, Path or PathRegex matchers can bypass path normalization. When Traefik uses path-based routing, requests containing URL-encoded restricted characters (/, \, Null, ;, ?, #) can bypass the middleware chain and reach unintended backends. For example, a request to http://mydomain.example.com/admin%2F could reach service-a without triggering my-security-middleware, bypassing security controls for the /admin/ path. This issue is fixed in versions 2.11.32 and 3.6.3.
