A researcher discovered a stored XSS vulnerability in a web application's internal notification system by injecting malicious HTML into a company name field. When users were invited to join the company, the unfiltered notification page executed the injected JavaScript payload for all invited users, demonstrating a critical vulnerability that a previous researcher had missed despite finding a related email injection issue.
