Error message

no templates provided for scan

What it means

ParseSMBTarget routes only two syntaxes to the SMB bridge: smb:// URLs and UNC paths starting with two backslashes or //. Anything else - drive letters, POSIX paths, file:// URLs - is rejected as 'not an SMB path' before any parsing happens.

Solutions

1. Use UNC form \\host\share\file or URL form smb://host/share/file
2. Keep local paths out of SMB-targeted input lists
3. Check the prefix before invoking SMB helpers when embedding nuclei

Example fix

# before
C:\shares\report.pdf
# after
\\fileserver\shares\report.pdf

import "strings"

func isSMBPath(s string) bool {
    s = strings.TrimSpace(s)
    return strings.HasPrefix(strings.ToLower(s), "smb://") ||
        strings.HasPrefix(s, "\\\\") ||
        strings.HasPrefix(s, "//")
}

When it happens

Trigger: Passing C:\file.txt, /mnt/share/file.txt, or file:///srv/x to the SMB reader; only the two supported prefixes enable the SMB code path.

Common situations: Mixing local paths and SMB targets in one list; assuming the parser auto-detects Windows drive paths.
