漏洞描述
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.
