CVE-2026-27629: InvenTree is an Open Source Inventory Management System. Prior to version 1.2.3, insecure server-side templates can be hijacked to expose secure information to the client. When generating custom batch codes, the InvenTree server makes use of a customizable jinja2 template, which can be modified by a staff user to exfiltrate sensitive information or perform code execution on the server. This issue requires access by a user with granted staff permissions, followed by a request to generate a custom batch code via the API. Once the template has been modified in a malicious manner, the API call to generate a new batch code could be made by other users, and the template code will be executed with their user context. The code has been patched to ensure that all template generation is performed within a secure sandboxed context. This issue has been addressed in version 1.2.3, and any versions from 1.3.0 onwards. Some workarounds are available. The batch code template is a configurable global setting which can be adjusted via any user with staff access. To prevent this setting from being edited, it can be overridden at a system level to a default value, preventing it from being edited. This requires system administrator access, and cannot be changed from the client side once the server is running. It is recommended that for InvenTree installations prior to 1.2.3 the `STOCK_BATCH_CODE_TEMPLATE` and `PART_NAME_FORMAT` global settings are overridden at the system level to prevent editing.
The exploitability of CVE-2026-27629 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2026-27629 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-27629, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-27629, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
