ThriveX-Server Missing Authorization in Article Endpoints

Executive Summary

ThriveX-Server through version 4.0 has a missing authorization vulnerability in the GET /api/article and /api/article/{id} endpoints. This flaw allows unauthenticated attackers to access unpublished draft articles or soft-deleted articles by either requesting sequential article IDs or using query parameters like isDraft=true or isDel=true. Attackers can retrieve full titles, descriptions, and content of non-public articles.

Impact Analysis

This vulnerability could allow unauthorized individuals to read sensitive or confidential article content that was meant to be private. If the articles contain proprietary, personal, or sensitive data, attackers could misuse this information for espionage, blackmail, or public disclosure. It undermines data confidentiality and could lead to reputational damage or legal consequences for affected organizations.
