Stored script injection via missing nonce validation
Published Feb 23, 2023 · Updated Apr 28, 2026
Cross-site request forgery in QuantumCloud WPBot 4.2.8 and earlier allows remote attackers to inject persistent web scripts via forged requests. The qcld_wb_chatbot_save_options handler accepts wp_chatbot_position_x and wp_chatbot_position_y values without valid nonce verification and stores them for later page rendering. Exploitation requires a logged-in site administrator to visit an attacker-controlled link or page, after which visitors execute the injected script and plugin settings can be reset.
