CVE-2026-53552

Goploy is an open-source automation deployment system. In versions 1.17.5 and prior, 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. At time of publication, there are no known publicly available patches.

What this means for your business

  • An attacker can use it remotely, over a network, with an ordinary user login, and without anyone at your company clicking anything.
  • FIRST's prediction model gives it a 0.2% chance of attack attempts being seen in the next 30 days, ranking above 10% of all known flaws.

What to do

  1. 1Ask your IT team or provider whether any of your systems use the affected product.
  2. 2If you do, follow the vendor's guidance. No patch reference has been published yet.
