CVE-2026-86668Public exploitNetwork attack vector

Cross-site scripting via unescaped upload parameters

Published Sep 8, 2026 · Updated Sep 8, 2026

Cross-site scripting in Aircheng iWebShop 5.0 through 5.15 allows remote attackers to inject script through image-upload parameters. The uploadFile function in controllers/pic.php places outerSrc or selectPhoto input into web output without adequate neutralization. A victim must open crafted content for the script to run in the iWebShop origin, where it can alter page content or perform session-authorized actions.
