CVE-2025-51628Public exploitNetwork attack vector

Unauthenticated document disclosure via guessable identifiers

Published Aug 5, 2025 · Updated Jul 5, 2026

IDOR in Agenzia Impresa Eccobook 2.81.1 and earlier allows remote attackers to read confidential documents through a crafted DocumentoId. The /Handler/PdfHandler.ashx endpoint accepts a sequential integer identifier and returns the referenced PDF without checking authorization. No authentication is required; enumerating identifiers exposes uploaded documents but provides no reported ability to modify them or interrupt service.
