Unless it’s vacuum sealed it will absorb water from the air and eventually go kind of manky. I don’t know how it is in all parts of the world, but most pasta here other than the exceptionally fancy stuff is just packaged loose in cardboard boxes that are in no way airtight.

If you stuck your spaghetti in one of those vacuum pumped storage containers to get all or most of the air out of it, it’ll probably last until the heat death of the universe regardless of what the packaging said on it.
