CVE-2026-103588

QloApps through 1.7.0 contains an insecure direct object reference vulnerability in OrderDetailController::displayAjaxSubmitRefundRequest() that allows authenticated customers to submit refunds for other customers' service lines. Attackers can submit foreign id_service_product_order_detail values with their own id_order to create refund records, cancel victims' service lines, and corrupt refund quantities.

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 1.6.0 through 1.7.0 contains a missing authorization vulnerability in the qlohotelreview module's AddReview AJAX action that allows unauthenticated attackers to submit reviews for arbitrary orders. Attackers can reuse the publicly exposed review_ajax_token and enumerate sequential id_order values to post fake ratings and reviews attributed to other customers.

QloApps through 1.7.0 contains an information disclosure vulnerability in OrderConfirmationController::init() that allows unauthenticated attackers to obtain guest order references and emails by supplying guest id_cart values. Attackers can iterate sequential id_cart values, read the Location redirect header, view booking details via guest-tracking, and convert guests into accounts with attacker-chosen passwords.

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 in the AdminHotelFeaturePricesSettings form that echoes feature_price_name and impact_value POST values unescaped after validation fails. Attackers can lure an authenticated back-office user into submitting a crafted request via a malicious link or auto-submitting form, executing JavaScript in their administrative session.
