CVE-2025-22873 is fixed in 10 products on 1 platform, first by ALAS2023-2025-977, released May 21, 2025. It is not reported as exploited. Patch Radar priority: Routine.
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.
