vulnerability
A persistent XSS vulnerability on eBay's My World profile section exploited a blacklist-based HTML filter that failed to block deprecated tags like <plaintext>, <fn>, and <credit>. The attacker chained this with event handlers, String.fromCharCode/eval to bypass character limits, missing CSRF protection, and unHTTPOnly cookies to create a self-propagating worm that could steal session tokens.
