CVE-2026-110131 in ThriveX-Server
Summary
by MITRE • 10/13/2026
ThriveX-Server through 4.0 contains a missing authorization vulnerability in the GET /api/article and /api/article/{id} endpoints that allows unauthenticated attackers to read unpublished draft and soft-deleted articles. Attackers can request sequential article ids or supply isDraft=true or isDel=true query parameters to retrieve full titles, descriptions and content of non-public articles.

The vulnerability identified in ThriveX-Server versions up to 4.0 represents a critical failure in access control mechanisms within the application's API layer. Specifically, the endpoints GET /api/article and GET /api/article/{id} lack proper authorization checks for sensitive content states. This flaw allows unauthenticated attackers to bypass intended security boundaries and retrieve data that should be restricted to authorized users or administrators. The core issue lies in the server's inability to distinguish between public-facing requests and those requiring authentication when accessing articles marked as drafts or soft-deleted, leading to a direct exposure of confidential information.
From a technical perspective, this vulnerability stems from an improper implementation of access control logic on the backend. When a client issues a GET request to these endpoints, the server processes the query parameters without verifying whether the requester has valid credentials or appropriate permissions for the specific resource state requested. Attackers can exploit this by either iterating through sequential article identifiers to discover existing records or by explicitly supplying query parameters such as isDraft=true or isDel=true. These parameters signal the database layer to include non-public items in the response payload, which the API then returns without any authentication gatekeeping. This behavior effectively neutralizes the security controls designed to keep draft and deleted content private during its lifecycle management phase.
The operational impact of this vulnerability is significant, as it leads to a severe breach of data confidentiality. Unauthenticated adversaries can harvest full titles, descriptions, and body content from unpublished articles that may contain sensitive business information, proprietary strategies, or personal data not intended for public consumption. Furthermore, soft-deleted articles might retain historical data or references to other secure resources, potentially aiding in further reconnaissance efforts. The ability to enumerate article IDs also facilitates automated scraping tools to map the entire repository of non-public content efficiently, turning a simple logic error into a large-scale information disclosure incident that could result in regulatory penalties and reputational damage depending on the nature of the exposed data.
This vulnerability aligns with CWE-284, which describes Improper Access Control, specifically highlighting failures where access control decisions are not enforced correctly for specific resources or states. In terms of offensive security frameworks, this behavior is characteristic of ATT&CK technique T1078, Valid Accounts, although in this case it applies to unauthenticated users exploiting misconfigured permissions rather than stolen credentials. It also relates to CWE-209, which covers the generation of error messages containing sensitive information, as the successful exploitation reveals structured data that should remain hidden. The lack of authentication checks on endpoints handling state-specific queries is a common pattern in poorly secured RESTful APIs where developers assume that draft or deleted states imply sufficient isolation without explicit access verification.
To mitigate this vulnerability, immediate remediation efforts must focus on enforcing strict authorization checks at the API gateway or controller level for all requests targeting article data. Developers should implement role-based access control (RBAC) policies that explicitly deny unauthenticated users from accessing resources marked as drafts or soft-deleted. It is essential to validate user permissions before querying the database, ensuring that only authenticated and authorized personnel can retrieve non-public content. Additionally, implementing rate limiting on these endpoints can help mitigate enumeration attacks where attackers iterate through sequential IDs. Regular security audits and static code analysis should be employed to detect similar access control flaws in other API endpoints, ensuring a comprehensive defense-in-depth strategy against information disclosure risks.
