CVE-2022-26488 Open this link in a new tabHow to fix?
Upgrade python/cpython to version 3.7.13, 3.8.13, 3.9.11, 3.10.3, v3.11.0a7 or higher.
Overview
Affected versions of this package are vulnerable to Untrusted Search Path in the Windows installer, which allows a local attacker to trigger a repair operation of the "Add Python to PATH" option to add incorrect additional paths to the system PATH variable, and then use search path hijacking to achieve escalation of privilege.
Note: This is only exploitable the "Add Python to PATH" option is selected. Default, per-user installs are also affected, but cannot be used for escalation of privilege. Manually adding the install directory to PATH is not affected.
Workaround
Users who are not able to upgrade to the fixed version can mitigate it by modifying an existing install to disable the "Add Python to PATH" or "Add Python to environment variables" option.
