CVSS 3.1
7.8 highCVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:NCVE-2023-6597
An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior.
The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means users which can run privileged programs are potentially able to modify permissions of files referenced by symlinks in some circumstances.
