CVE-2026-110218 in Aureus ERP
Summary
by MITRE • 10/13/2026
Aureus ERP through 1.6.0 contains an authorization bypass vulnerability that allows unauthenticated attackers to read unpublished draft blog posts via the customer-facing post view page. Attackers who know or guess a post slug can retrieve the full title, content, image, tags, author and publish date because PostResource skips authorization and ViewPost ignores is_published.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified in Aureus ERP versions up to 1.6.0 represents a critical failure in access control mechanisms within its content management subsystem. Specifically, the flaw resides in how the application handles requests for blog post data through its customer-facing interface. The core technical issue stems from an improper implementation of authorization checks on the server side. When a user attempts to view a specific blog post by providing a unique identifier known as a slug, the backend resource responsible for retrieving this data, referred to as PostResource, fails to enforce any authentication or authorization requirements before processing the request. This design oversight means that the system does not verify whether the requesting entity has valid credentials or appropriate permissions to access the requested content.
Furthermore, even if an attacker were somehow authenticated, the logic governing the display of post details contains a significant logical flaw in the ViewPost component. This module is responsible for determining which fields and metadata should be returned to the client based on the state of the blog post. However, it ignores the is_published flag associated with each post entry in the database. In standard content management systems, this boolean field dictates whether a piece of content is visible to the public or restricted to internal users during its drafting phase. By disregarding this status indicator, the application treats unpublished drafts as if they were fully published articles, thereby exposing sensitive information that was intended to remain confidential until official release.
The operational impact of this vulnerability allows unauthenticated attackers to retrieve comprehensive details about draft blog posts without any prior login or permission. An attacker who can guess or enumerate valid post slugs can access the full title, body content, associated images, tags, author identity, and scheduled publish dates. This exposure poses a severe risk to organizational integrity and security posture. The leakage of unpublished content may reveal strategic business plans, internal communications, product roadmaps, or personal data of authors before they are ready for public consumption. Additionally, the disclosure of author information could facilitate targeted social engineering attacks against employees, while access to draft images might expose proprietary assets or sensitive visual materials that were not meant for external distribution.
From a classification perspective, this vulnerability aligns with CWE-284, which describes Improper Access Control, as it involves unauthorized actors bypassing intended restrictions on resource access. It also maps directly to the MITRE ATT&CK framework under T1078, specifically Valid Accounts or Default Accounts if authentication were required, but more accurately fits within general reconnaissance and data exfiltration tactics where an attacker gathers information about system configurations and content structures without detection. The lack of proper validation on input parameters like slugs combined with the failure to check publication status exemplifies a classic broken access control scenario often seen in web applications that prioritize convenience over security rigor during development phases.
To mitigate this vulnerability, immediate remediation steps should focus on enforcing strict authorization checks at every level of the request lifecycle. The PostResource component must be updated to require valid authentication tokens or session cookies before any data retrieval occurs. Additionally, the ViewPost logic needs to explicitly check the is_published flag and return an error or empty response for any posts where this value is false. Implementing proper input validation on slugs can also help prevent enumeration attacks by ensuring that only syntactically correct and existing identifiers are processed. Regular security audits and code reviews focusing on access control lists will further ensure that similar logical flaws do not persist in future releases of the Aureus ERP platform.
