Official description

Cachet is an open-source status page system. Versions 2.4.1 and earlier have a stored Cross-Site Scripting (XSS) vulnerability in the incident creation form, allowing an authenticated attacker to inject malicious HTML/JavaScript that executes in the browser of any user who views the status page, potentially leading to session token theft and account takeover.
