CVE-2026-110221

QloApps through 1.7.0 contains a reflected cross-site scripting vulnerability in the back-office room type editor's length of stay fields. Attackers can induce authenticated administrators to submit crafted POST requests with malicious payloads in restriction_min_los and restriction_max_los parameters, executing arbitrary JavaScript in the victim's administrative session.

QloApps through 1.7.0 contains a reflected cross-site scripting vulnerability in the back-office Hotel Reservation System Book Now search, where date_to and id_room_type parameters are copied into template variables without validation. Attackers can craft a malicious link containing a JavaScript payload in these parameters that executes in an authenticated administrator's session when the victim follows the link.

Unrestricted file upload in the hotel review feature in QloApps versions 1.7.0 and earlier allows remote unauthenticated attackers to achieve remote code execution.

QloApps through 1.7.0 contains an improper access control vulnerability in AdminSlipController that allows hotel-restricted back-office employees to access credit slips of all hotels. Attackers can list, export as PDF, mark as redeemed, and generate store-credit vouchers from other hotels' refund records, exposing customer identities and amounts.

QloApps through 1.7.0 contains a broken access control vulnerability that allows hotel-restricted back-office employees to create room types under unassigned hotels by supplying an arbitrary id_hotel. Attackers can enumerate all hotels via the unfiltered room type form selector and post foreign hotel IDs to AdminProductsController, creating rooms and inventory under other hotels.

QloApps through 1.7.0 contains a reflected cross-site scripting vulnerability in AdminSearchConfController::processSave() that echoes rejected alias and search values unescaped in validation errors. Attackers can induce an authenticated back-office user to submit a crafted request, executing JavaScript in that user's administrative session.

QloApps through 1.7.0 contains a reflected cross-site scripting vulnerability that allows remote attackers to inject scripts through the price parameter of the back-office Additional Facilities form. Attackers can induce an authenticated back-office user to submit a crafted request whose unescaped price value is re-rendered after failing validation, executing JavaScript in the administrative session.

QloApps through 1.7.0 contains an insecure direct object reference vulnerability in back-office AJAX handlers that skip htl_access hotel checks.

QloApps through 1.7.0 contains an authorization bypass vulnerability in AdminHotelRoomsBookingController::postProcess() that allows restricted back-office employees to access other hotels' data by supplying an id_hotel parameter. Attackers can modify the id_hotel URL parameter on the Book Now page to view room availability and booking status of hotels outside their assigned profile access.

QloApps through 1.7.0 contains an authorization bypass vulnerability in AdminProductsController::ajaxProcessBulkUpdateRooms. Hotel-restricted back-office employees can modify rooms of other hotels by submitting foreign room IDs in the id_rooms parameter, changing status, floor, comments, or inactive dates.
