This is a Vulnerable Lab
ratnews.thexssrat.com is an intentionally vulnerable web application built by
The XSS Rat as a safe, legal environment for practising offensive security techniques.
You have explicit permission to attack this application. Do not use what you learn here against systems you do not own.
Why this lab exists
Real bug bounty hunters and penetration testers need live targets to sharpen their skills. This lab mirrors a realistic content-delivery stack
— a FastAPI app with a database, user accounts, an admin API, and RSS aggregation — so you can practise against something that behaves like a real application,
document your findings, and build a repeatable methodology without any legal risk.
What vulnerabilities are hidden here
→Reflected & Stored XSS — unsanitised user input rendered in the browser
→SQL Injection — boolean-based blind injection in search and filter endpoints
→SSRF — server-side request forgery via RSS feed ingest
→IDOR — insecure direct object references in user and preference endpoints
→Auth bypass & API key exposure — weak admin token enforcement and session manipulation
→Open redirect — unsafe next parameter handling after login
Attackers Target Rejetto HFS Flaw That Enables Admin Session Forgery and RCE
A critical security flaw impacting Rejetto HTTP File Server (HFS) is witnessing active exploitation attempts, according to VulnCheck.
The vulnerability in question is CVE-2026-61500 (CVSS score: 9.3), a case of session forgery stemming from the use of a weak pseudo-random number generator (PRNG) that can lead to a predictable key, which an attacker can then use to gain unauthorized access and
