CVE-2025-22873

3.8 lowEPSS 0.2%

Low (3.8) in golang go. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in stdlib 1.23.9, 1.24.3.

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.
