data/cura-engine-4.8/src/communication/CommandLine.cpp:360:9: [4] (buffer) strcpy:
Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused).
strcpy(paths, search_path_env); //Necessary because strtok actually modifies the original string, and we don't want to modify the environment variable itself.
data/cura-engine-4.8/src/utils/Date.cpp:43:10: [4] (buffer) sscanf:
The scanf() family's %s operation, without a limit specification, permits
buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
different input function.

int char_count = sprintf(buffer, format, coord);
data/cura-engine-4.8/tests/InfillTest.cpp:22:14: [4] (format) snprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
std::snprintf(buff, buff_size, format_string.c_str(), args...);
