In early 2026, Microsoft released a "refreshed" web experience that many users described as "cracked" or broken due to bugs:
The vulnerability, which was later patched by GroupMe, was caused by a flawed authentication mechanism in the web application. Specifically, the issue arose from the way GroupMe handled user session cookies, which are used to authenticate users and maintain their session state. An attacker could exploit this vulnerability by manipulating the session cookies, effectively bypassing authentication and gaining unauthorized access to user accounts.
Over the next few weeks, I immersed myself in the world of bug bounty hunting and responsible disclosure. I learned about the various tools and techniques used by hackers to identify vulnerabilities. I also gained insight into the challenges faced by developers in securing their applications.
