Unauthenticated arbitrary deletion via ineffective traversal guard
Published Apr 6, 2026 · Updated Apr 6, 2026
Path traversal in goshs before 2.0.0-beta.3 allows remote attackers to delete arbitrary files and directories through an HTTP request. The deleteFile handler cleans the path before decoding it, reports a traversal error without returning, then passes the decoded path to filepath.Join and os.RemoveAll. The default configuration requires no authentication or flags, and a double-encoded path sent with the delete query can remove any object accessible to the server process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
