`ModuleSearch` decides whether to filter protected pages out of search results based on the current value of `contao.search.index_protected`, but the authorisation data lives per row in `tl_search`. Turning the setting off removes the filter without removing the rows, so protected pages that were indexed while it was on are returned to unauthenticated visitors such as title, URL and context snippet, even though the pages themselves still answer 401. ## Impact Disclosure of member-only page titles, URLs and indexed text to unauthenticated visitors through the site search. The pages themselves remain access-controlled, so this is not a page-access bypass. ## Credits This security vulnerability was found by @iRevivalx .
