Goploy: Cross-namespace IDOR and RCE via body-supplied row id in project and project_file handlers

### Summary `Project.AddFile`, `Project.EditFile`, `Project.RemoveFile`, and `Project.Edit` in `cmd/server/api/project/handler.go` accept a project or project-file row id from the JSON body and act on it without checking that the project belongs to the caller's namespace. The corresponding `model.ProjectFile.GetData` and `model.Project.GetData` queries filter only by row id. A user holding the `manager` role (or any role that includes the `FileSync` / `EditProject` permission) in their own namespace can read, write, or delete files in any project across the install, and can rewrite any project's git remote URL by submitting the foreign id in the body. The git-URL primitive escalates to RCE on the next deploy because `Edit` runs `git remote set-url` on the project's working tree. ### Affected `zhenorzz/goploy` `develop` HEAD as of 2026-05-27. Verified against the `zhenorzz/goploy:1.17.5` Docker image (`docker.io/zhenorzz/goploy@sha256:69d08e1d16d7a7167426c89456c4bcef8e077a16554a4067ff258fff26d5cd44`). The four handlers and the model lookups have been in this shape across the file API and project metadata API. ### Vulnerable code `cmd/server/api/project/handler.go::AddFile` (creates file under any project's directory; body controls `projectId`): ```go func (Project) AddFile(gp *server.Goploy) server.Response { type ReqData struct { ProjectID int64 `json:"projectId" validate:"required,gt=0"` Content string `json:"content" validate:"required"` Filename string `json:"filename" validate:"required"` } var reqData ReqData if err := gp.Decode(&reqData); err != nil { ... } filePath := path.Join(config.GetProjectFilePath(reqData.ProjectID), reqData.Filename) // ... os.Create(filePath); file.WriteString(reqData.Content) id, err := model.ProjectFile{ProjectID: reqData.ProjectID, Filename: reqData.Filename}.AddRow() } ``` `cmd/server/api/project/handler.go::EditFile` (overwrites file content; body controls file id, server derives project from the file row): ```go func (Project) EditFile(gp *server.Goploy) server.Response { type ReqData struct { ID int64 `json:"id" validate:"required,gt=0"` Content string `json:"content" validate:"required"` } var reqData ReqData if err := gp.Decode(&reqData); err != nil { ... } projectFileData, err := model.ProjectFile{ID: reqData.ID}.GetData() // ... os.Create(path.Join(config.GetProjectFilePath(projectFileData.ProjectID), projectFileData.Filename)) file.WriteString(reqData.Content) } ``` `cmd/server/api/project/handler.go::RemoveFile` (deletes file row + on-disk file by body id): ```go func (Project) RemoveFile(gp *server.Goploy) server.Response { type ReqData struct { ProjectFileID int64 `json:"projectFileId" validate:"required,gt=0"` } var reqData ReqData if err := gp.Decode(&reqData); err != nil { ... } projectFileData, err := model.ProjectFile{ID: reqData.ProjectFileID}.GetData() if err := os.Remove(path.Join(config.GetProjectFilePath(projectFileData.ProjectID), projectFileData.Filename)); err != nil { ... } } ``` `cmd/server/api/project/handler.go::Edit` (updates any project's metadata; on URL change runs `git remote set-url` in the project working tree): ```go func (Project) Edit(gp *server.Goploy) server.Response { // ... ReqData has ID, Name, URL, Branch, Script, etc. projectData, err := model.Project{ID: reqData.ID}.GetData() model.Project{ID: reqData.ID, Name: reqData.Name, URL: reqData.URL, ...}.EditRow() if reqData.URL != projectData.URL { srcPath := config.GetProjectPath(projectData.ID) cmd := exec.Command("git", "remote", "set-url", "origin", reqData.URL) cmd.Dir = srcPath } } ``` `internal/model/project_file.go::ProjectFile.GetData` filters only by row id, no namespace join: ```go func (pf ProjectFile) GetData() (ProjectFile, error) { err := sq. Select("id, project_id, filename, insert_time, update_time"). From(projectFileTable). Where(sq.Eq{"id": pf.ID}). ... } ``` `internal/server/route.go::Route.hasPermission` checks only namespace-level permission ids; nothing in the request flow verifies that the body-supplied project id belongs to `gp.Namespace.ID`: ```go func (r Route) hasPermission(permissionIDs map[int64]struct{}) error { if len(r.permissionIDs) == 0 { return nil } for _, permissionID := range r.permissionIDs { if _, ok := permissionIDs[permissionID]; ok { return nil } } return errors.New("no permission") } ``` ### Reachable Any logged-in user assigned the `manager` role in their own namespace can call `/project/addFile`, `/project/editFile`, `/project/removeFile`, and `/project/edit`. The seeded `manager` role (`role.id = 1`) is granted both `FileSync` (`permission.id = 68`) and `EditProject` (`permission.id = 17`) by `database/goploy.sql`. Multi-tenant deployments typically assign `manager` to each tenant's project owner; once a tenant's manager holds these permissions in their own namespace, they hold them globally for these four endpoints. ### Proof of concept Setup against the published Docker image: ```bash docker network create goploy-net docker run -d --name goploy-mysql --network goploy-net \ -e MYSQL_ROOT_PASSWORD=goploy123 -e MYSQL_DATABASE=goploy \ mysql:8.0 --default-authentication-plugin=mysql_native_password # Wait for MySQL, then load schema docker cp database/goploy.sql goploy-mysql:/tmp/goploy.sql docker exec goploy-mysql sh -c 'mysql -uroot -pgoploy123 goploy < /tmp/goploy.sql' # Mount goploy.toml pointing DB at goploy-mysql:3306 docker run -d --name goploy-app --network goploy-net -p 18080:80 \ -v $PWD/repo:/opt/goploy/repository \ zhenorzz/goploy:1.17.5 ``` Set up two namespaces and two non-super-manager users, each assigned `manager` (role_id=1) only in their own namespace: ```bash # Admin login (default account admin / admin!@# requires fi…
