SeaweedFS是SeaweedFS团队开源的一个用于blob、对象、文件和数据湖的快速分布式存储系统。 SeaweedFS 4.30之前版本存在路径遍历漏洞,该漏洞源于S3 API网关和Iceberg REST目录网关在构建路由器时禁用路径清理,导致URL中的..段保留,从而可能使攻击者通过特制请求访问其他存储桶。

|---|---|---|---|
| 1 | SeaweedFS versions through 4.29 build the S3 API and Iceberg REST catalog routers with mux.NewRouter().SkipClean(true), which disables URL path cleaning. A `..` segment in the request path therefore survives routing and reaches the handlers unnormalised, so a request such as `PUT /bucket-A/../evil-bucket/key` is matched as bucket=bucket-A with object=../evil-bucket/key. The captured object key is then joined into a filer path where the `..` is collapsed server-side, so the write lands in evil-bucket while authorisation is evaluated against bucket-A, enabling cross-bucket file write. | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-54917.yaml | POC详情 |
