CVE-2026-56857 1 Go Standard Library 2 Internal/syscall/windows, Os 2026-10-09 9.8 Critical
On Windows, when the target of Root.Mkdir or Root.MkdirAll is a junction pointing to an empty location, the operation can create a directory at the junction target even when that target is located outside the root. This only applies to operations where the last path component is a junction (path/to/junction, but not path/junction/target).
CVE-2026-39822 2 Go Standard Library, Golang 2 Os, Go 2026-07-10 7.8 High
On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /. For example, 'root.Open("symlink/")' will open "symlink" even when "symlink" is a symbolic link pointing outside of the root.
CVE-2026-27139 2 Go Standard Library, Golang 2 Os, Go 2026-04-21 2.5 Low
On Unix platforms, when listing the contents of a directory using File.ReadDir or File.Readdir the returned FileInfo could reference a file outside of the Root in which the File was opened. The impact of this escape is limited to reading metadata provided by lstat from arbitrary locations on the filesystem without permitting reading or writing files outside the root.
CVE-2025-22873 2 Go Standard Library, Golang 2 Os, Go 2026-02-10 3.8 Low
It was possible to improperly access the parent directory of an os.Root by opening a filename ending in "../". For example, Root.Open("../") would open the parent directory of the Root. This escape only permits opening the parent directory itself, not ancestors of the parent or files contained within the parent.
