Description

An issue was discovered in Python 3.11 through 3.11.4. If a path containing '\0' bytes is passed to os.path.normpath(), the path will be truncated unexpectedly at the first '\0' byte. There are plausible cases in which an application would have rejected a filename for security reasons in Python 3.10.x or earlier, but that filename is no longer rejected in Python 3.11.x.
Python 3.11 os.path.normpath() function is vulnerable to path truncation if a null byte is inserted in the middle of passed path. This may result in bypass of allow lists if implemented before the verification of the path.
