Stored XSS via unsanitized long URL input
Published Nov 27, 2023 · Updated Nov 21, 2024
Stored XSS in SourceCodester Responsive URL Shortener Web App 1.0 allows remote authenticated users to execute script via a long URL. The Long URL handler accepts a POSTed URL without adequate sanitization, stores it, and renders it on the home page as executable markup. A low-privileged account can plant the payload, but script execution requires another user to visit the affected home page; the resulting code runs in that user's browser context.
