Should be alright. zsh is even the one shell where you don't
need the quotes around $file.

Maybe your "cmd" is poorly written and can't cope with filenames
containing blanks.

Problems would come for lines that have leading or trailing
blanks or have backslashes.

Try (with GNU xargs)

xargs -d '\n' -n1 cmd < file.txt

Or

for line (${(f)"$(cat file.txt)"}) cmd -- $line

or

while IFS= read -r line; do
  cmd -- $line
done
