SeaweedFS <= 4.29 - Path Traversal File Write

SeaweedFS versions through 4.29 build the S3 API and Iceberg REST catalog routers with mux.NewRouter.SkipCleantrue, 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...
