XWiki allows unregistered users to access private pages information through REST endpoint

Impact

Protected pages are listed when requesting the REST endpoints /rest/wikis/[wikiName]/pages even if the user doesn't have view rights on them. It's particularly true if the entire wiki is protected with "Prevent unregistered user to view pages": the endpoint would still list the pages of the wiki (actually it only impacts the main wiki due to XWIKI-22639).

Patches

The problem has been patched in XWiki 15.10.14, 16.4.6, 16.10.0RC1. In those versions the endpoint can still be requested but the result is filtered out based on pages rights.

Workarounds

There's no workaround except upgrading or applying manually the changes of the commits (see references) in xwiki-platform-rest-server and recompiling / rebuilding it.
