CWE ID 269

Summary

CVE-2023-6507 is a vulnerability affecting the `subprocess` module in CPython 3.12.0 on POSIX platforms. This issue arises when using an empty list as the value for the `extra_groups` parameter. The logic regressed, causing the `setgroups` system call not to be made before executing a new process. This omission leaves the original process's groups unchanged, potentially leading to security concerns when running the affected CPython processes with elevated privileges, such as `root`. The issue has been resolved in CPython 3.12.1 and does not impact other stable releases.
