CVE-2025-22873 unimportant priority: Debian including 3 source packages (golang-1.15, golang-1.19, golang-1.24), 3 status rows across 3 suites (bookworm, bullseye, trixie): resolved 3.
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.
