Overview
CVE-2025-66424 is a medium severity vulnerability affecting Tryton, an open-source business management system. Specifically, versions 6.0 before 7.6.11 are susceptible to a flaw where access rights are not properly enforced during data export operations. This could allow unauthorized users to export sensitive data they should not have access to. Patches are available in versions 7.6.11, 7.4.21, 7.0.40, and 6.0.70.
Technical Details
The vulnerability stems from insufficient access control checks within the data export functionality of Tryton. Without proper validation of user permissions before initiating an export, malicious or compromised accounts could potentially bypass intended restrictions and extract data from various modules within the Tryton system. This could include customer data, financial records, or other confidential business information.
This vulnerability exists due to a logical error in how Tryton handles access control requests related to the data export feature. The system fails to adequately verify that the user initiating the export process has the necessary permissions for all the data being exported.
CVSS Analysis

- Attack Vector: Network (AV:N)
- Attack Complexity: Low (AC:L)
- Privileges Required: Low (PR:L)
- User Interaction: None (UI:N)
- Scope: Unchanged (S:U)
- Confidentiality: High (C:H)
- Integrity: None (I:N)
- Availability: None (A:N)
This score indicates that the vulnerability can be exploited over the network, requires low privileges to exploit, and primarily impacts the confidentiality of the data.
