vulnerability
Technical writeup demonstrating how arbitrary XSS vulnerabilities in Outlook and Twitter were exploited by chaining cookie injection attacks with browser-specific parsing differences. The researchers discovered endpoints that reflected user input into Set-Cookie headers, then leveraged Safari's comma-delimited cookie parsing to inject malicious ClientId/session cookies that would execute stored XSS payloads on victim browsers.
