CVE-2026-94497 in jshERP
Summary
by MITRE • 09/21/2026
jshERP through 3.6 fails to validate object ownership in by-id info, update, and delete endpoints across multiple resource types. Authenticated users can read, modify, and delete other users' business objects by submitting direct object identifiers without authorization checks.

The vulnerability identified in jshERP versions through 3.6 represents a critical failure in access control mechanisms, specifically categorized under CWE-284 Improper Access Control. This flaw manifests as an Insecure Direct Object Reference (IDOR) issue within the application's backend logic governing business object management. The core technical deficiency lies in the absence of server-side validation to ensure that the authenticated user initiating a request possesses legitimate ownership or administrative privileges over the specific resource identified by the provided identifier. Instead of verifying that the subject of the action matches the identity of the actor, the system blindly trusts the input parameters supplied via HTTP requests for information retrieval, modification, and deletion operations.
This architectural weakness allows any authenticated user to manipulate data belonging to other users within the same tenant or organization. By simply altering the unique identifier associated with a business object in API calls targeting by-id info, update, and delete endpoints, an attacker can bypass intended authorization checks. For instance, if User A attempts to view details of a record owned by User B, the system returns the data without confirming that User A has permission to access it. Similarly, updates or deletions performed on records not belonging to the requesting user are executed successfully, leading to unauthorized state changes and potential data loss across multiple resource types supported by the ERP platform.
The operational impact of this vulnerability is severe, compromising both confidentiality and integrity within the enterprise environment. Confidentiality is breached as sensitive business information, such as financial records, customer details, or internal communications stored in these objects, becomes accessible to unauthorized personnel. Integrity is compromised because malicious actors can alter critical data fields or permanently delete essential business assets, potentially disrupting operational workflows and causing significant financial or reputational damage. Since the vulnerability affects multiple resource types, the scope of potential harm extends across various functional modules of the ERP system, amplifying the risk profile significantly for organizations relying on this software for core operations.
From a threat modeling perspective aligned with MITRE ATT&CK frameworks, this behavior corresponds to techniques involving unauthorized access and data manipulation through API abuse. Attackers can leverage automated tools to iterate through sequential identifiers or guess valid object IDs to enumerate and exfiltrate large volumes of sensitive data efficiently. The lack of proper ownership validation means that the application fails to enforce least privilege principles, allowing lateral movement within the dataset once initial authentication is achieved. This scenario highlights a common pitfall in web development where developers assume that session-based authentication implicitly grants permission for all actions performed by that user, neglecting explicit object-level authorization checks.
To mitigate this vulnerability, immediate remediation efforts must focus on implementing robust server-side access control logic. Developers should enforce strict ownership verification before processing any read, update, or delete request against a specific resource identifier. This involves querying the database to confirm that the record's owner ID matches the authenticated user's identity or verifying administrative roles where applicable. Additionally, adopting principle of least privilege in API design and implementing comprehensive logging for access control failures can aid in detecting potential exploitation attempts. Regular security audits focusing on authorization logic across all endpoints are essential to prevent similar flaws from persisting in future releases of the software.
