Okay, here is something I made up right now. Try to run it only once per document :P as it attempts to ‘clean up’, but hyperlinks may use so many different objects, it’s hard to get that right.
All it requires are objects marked with one of two object styles: ‘prev’ and ‘next’. The objects may appear on any single page, or reside on a Master Page. Only one level deep! That is, not on a master page based on a master page, which in turn is based on a master page … (and so on) … Keep it simple!
After running the script, master page items are overridden, and all ‘prev’ objects will link to the previous page and ‘next’ to the next one. A ‘prev’ link on the first page will not get linked, and neither will a ‘next’ link on the *last* page of a document.
Here is the code; also downloadable from my site as https://www.jongware.com/binaries/linkprevnextpages.zip

processPage(app.activeDocument.pages[p]);

{
var obj, link, e;
/* search the applied master */
if (a_page.appliedMaster != null)
{
for (obj=0; obj<a_page.appliedMaster.pageItems.length; obj++)
{
if (a_page.appliedMaster.pageItems[obj].appliedObjectStyle)
{
if (a_page.appliedMaster.pageItems[obj].appliedObjectStyle.name == ‘prev’ &&
a_page.documentOffset > 0)

try {
a_page.appliedMaster.pageItems[obj].override (a_page);
} catch (e)
{
/* no problem */
