AI-suggested
Upgrade icloudpd to version 1.24.0 or later, which contains the fix for this vulnerability. Alternatively, ensure the environment uses Python 3.11 or later on Windows to avoid the unsafe path handling. No other mitigation is indicated.
Description
CVE-2024-49766 is a vulnerability in icloudpd versions 1.21.0 through 1.23.x on Windows systems running Python versions earlier than 3.11. The issue arises because Werkzeug's safe_join() function relies on os.path.isabs() to detect absolute paths, but on these Python versions on Windows, os.path.isabs() does not correctly identify UNC paths (e.g., //server/share) as absolute. This can lead to unsafe path joins, potentially allowing unintended access to data. The vulnerability is fixed in icloudpd version 1.24.0.
