Unauthenticated Plugin Metadata Disclosure in InvenTree

Publication date: 2026-09-21

Last updated on: 2026-09-21

Assigner: GitHub, Inc.

Description
InvenTree is an Open Source Inventory Management System. Prior to 1.4.0, PluginSettingList, PluginAllSettingList, and PluginSettingDetail set GlobalSettingsPermissions without the IsAuthenticated permission used by the project default and equivalent global-settings endpoints. GlobalSettingsPermissions returns true for safe methods, while AuthRequiredMiddleware exempts /api/ paths, so an unauthenticated caller can retrieve plugin names, setting keys, descriptions, types, choices, and non-protected configuration values through /api/plugin/settings/ and the per-plugin settings endpoints. Protected secret values remain masked as three asterisks, limiting the issue to metadata and non-secret configuration disclosure. This issue is fixed in version 1.4.0.

Executive Summary

CVE-2026-61746 is a vulnerability in InvenTree, an open-source inventory management system. It affects versions 1.3.5 and earlier. The issue involves three plugin-settings GET endpoints that are accessible without authentication due to incorrect permission class configuration. The GlobalSettingsPermissions class allows unauthenticated access to GET requests, exposing plugin settings metadata like names, keys, descriptions, types, choices, and non-protected configuration values. Secret values remain masked.

The endpoints affected are /api/plugin/settings/, /api/plugin/<slug>/settings/, and /api/plugin/<slug>/settings/<key>/. The vulnerability stems from GlobalSettingsPermissions.has_permission returning true for safe methods without checking authentication, combined with AuthRequiredMiddleware exempting /api/ paths.

Detection Guidance

Check if your InvenTree instance is running a vulnerable version (1.3.5 or earlier) by inspecting the version in the web interface or API response. Test unauthenticated access to the endpoints /api/plugin/settings/, /api/plugin/<slug>/settings/, and /api/plugin/<slug>/settings/<key>/ to see if they return plugin metadata without requiring login.

Impact Analysis

An unauthenticated attacker could access plugin settings metadata and non-secret configuration values through the affected endpoints. This includes plugin names, setting keys, descriptions, types, choices, and non-protected values. While secret values are masked, the exposure of metadata could aid in further attacks or reconnaissance of the system.

Compliance Impact

The vulnerability allows unauthenticated access to plugin settings metadata and non-secret configuration values, which could expose sensitive system information. This may violate data protection principles under GDPR (e.g., unauthorized access to personal or system data) and HIPAA (e.g., exposure of configuration details related to healthcare systems). However, since secret values are masked, the direct impact on regulated data is limited.

Mitigation Strategies

Upgrade InvenTree to version 1.4.0 or later to apply the security fix. If immediate upgrade is not possible, restrict network access to the vulnerable endpoints or implement additional authentication layers for these API paths.
