Post-authentication script execution via unvalidated redirect parameter
Published Mar 2, 2026 · Updated Mar 2, 2026
DOM-based XSS in Wethink Technology Inc. 720yun pano-sdk 0.5.877 allows remote attackers to execute JavaScript through a crafted login link. The LoginComp and SignupComp modules parse the redirect query parameter and assign it to window.location navigation without validating its scheme or origin. Exploitation requires a victim to open the crafted link and complete authentication, after which script runs in the authenticated browser context and can read session data or perform actions as that user.
