This looks like AI blogspam. It’s annoyingly vague about the important details and padded with trivia. The original article by the discoverer of the vulnerabilities is much better: n8n RCE(s): A Tale of 4 Acts (CVE-2025-68613 & CVE-2026-25049)
Excellent post, thanks for submitting. I personally am messing about with Haskell these days, so also wondered, "could this happen here?" In Haskell, the type-checking machinery is also done at compile-time, not in the runtime. I think the answer in this case is no, because the other aspect at play in this vulnerability is essentially a deserialization attack. That is, the vulnerable runtime is accepting an input that is already a JavaScript object, which might be executable code. Anyway, fun to think about.
