## P1 Critical: XSS Vulnerability in REVIEW_ME.tsx via dangerouslySetInnerHTML Exposes User Data
A critical security flaw has been identified in the codebase, exposing the application to cross-site scripting (XSS) attacks. The vulnerability originates in the `REVIEW_ME.tsx` component, which renders user-controlled ticket descriptions as raw HTML without sanitization. This allows any user with ticket creation privileges to inject and execute arbitrary JavaScript in the context of other users' browsers, creating a direct path for session hijacking and data theft.

The root cause is a single line of code at `src/REVIEW_ME.tsx:71`. The component uses React's `dangerouslySetInnerHTML` prop to directly inject the `ticket.description` value into the DOM. Since ticket descriptions are user-supplied input, an attacker can craft a description containing malicious HTML, such as `<img src=x onerror=alert(1)>`. When another user views the TicketDashboard, the script payload executes automatically, demonstrating a textbook XSS vulnerability that ranks among the OWASP Top 10 security risks.

The immediate risk is severe. This is not a theoretical flaw but a live, exploitable vector. An attacker could leverage this to steal authentication cookies, perform actions on behalf of logged-in users, exfiltrate sensitive data, or deface the application interface. The proposed fix is straightforward: replace the dangerous HTML injection with safe text rendering using `<div>{ticket.description}</div>`. Until this patch is deployed, the application remains critically vulnerable to client-side attacks initiated through a basic user function.
