This is a native behavior for pagination on a Hubspot blog. If you test the url "cat/article/page/1", you will arrive on page 1 of the category, equivalent to the URL "/cat/article". So this has no impact on your SEO since the tagged page exists.
If you want, you can always redirect from "/cat/article/page/1" to "/cat/article".

While the impact of having a page/1 duplicate is negligible, your response is categorically false.
This is the literal definition of duplicate content, and perhaps more importantly internal site architecture on every paginated page will prioritize page/1 over /blogname, /tag/.* or /category/.* The fact that the "tagged page exists so it has no impact on SEO" is wildly innacurate.
Redirecting the page is the solution but it's not an elegant solution, especially if you have a lot of paginated series on your site. Could also technically implement a canoncical via GTM but that's also not elegant.
