Database disclosure via unprepared hint_ids query
Published Mar 21, 2026 · Updated Mar 21, 2026
SQL injection in Pre* Party Resource Hints 1.8.20 and earlier allows remote authenticated users to extract database data via hint_ids. The pprh_update_hints AJAX action insufficiently escapes the user-supplied hint_ids value and incorporates it into an unprepared SQL query, so injected SQL changes the existing query. Subscriber-level access is sufficient, and successful exploitation exposes sensitive information stored in the WordPress database.
