Jonathan Bouman discovered a persistent XSS vulnerability in LinkedIn's article embed feature by exploiting unvalidated Open Graph tags, specifically the og:video tag, to inject malicious HTML and create fake phishing login screens that could steal user credentials. The vulnerability leverages LinkedIn's content embedding functionality which processes Open Graph metadata without proper validation, allowing attackers to inject arbitrary content into iframes on LinkedIn articles.
