High [CVE-2026-39822] Go os.Root: Symlink following vulnerability allows directory traversal
CVE-2026-39822Source published Source updated
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. This vulnerability allows an attacker to bypass intended directory restrictions by crafting a path that ends with a symbolic link and a trailing slash. When a file is opened in `os.Root` with such a path, the symbolic link is improperly followed, potentially leading to access to locations outside of the defined root directory. This could result in information disclosure or unauthorized file system access. A flaw was found in Go's os.Root implementation. This is because…
