Summary

The Bello - Directory & Listing WordPress theme before 1.6.0 did not sanitise the bt_bb_listing_field_price_range_to, bt_bb_listing_field_now_open, bt_bb_listing_field_my_lng, listing_list_view and bt_bb_listing_field_my_lat parameters before using them in a SQL statement, leading to SQL Injection issues.

Remediation & mitigations

  1. Update to version 1.6.0, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
