AI-suggested
A patch is available to address this vulnerability. Users should upgrade to a fixed version of the affected software or ensure their Python environment is version 3.11 or later on Windows. Applying the official patch or upgrading Python will mitigate the risk. No additional vendor advisory details contradict this guidance.
Description
CVE-2024-49766 is a vulnerability affecting Mapproxy on Windows systems running Python versions earlier than 3.11. It stems from Werkzeug's safe_join() function incorrectly handling UNC paths as absolute due to reliance on os.path.isabs() in these Python versions. This flaw can lead to unsafe path joins and potentially unintended data access. Systems using Python 3.11 or later, or non-Windows platforms, are not affected. A patch is available to remediate this issue.
