Executive Summary

CVE-2026-78160 is an authorization bypass vulnerability in Dolibarr ERP versions up to 18.0.10/22.0.5/23.0.3. It allows users with only the 'Create/modify his own user information' permission to modify notes of any user, including administrators, by manipulating the ID parameter in the /user/note.php file. The issue stems from improper server-side verification of user permissions.

Detection Guidance

To detect this vulnerability, check if your Dolibarr instance is running a vulnerable version (up to 18.0.10/22.0.5/23.0.3). Inspect the /user/note.php file for improper authorization checks on the ID parameter. Look for unauthorized modifications to user notes, especially by non-admin users.

Impact Analysis

Attackers could exploit this to inject false information into admin-facing interfaces, compromise sensitive metadata, or escalate privileges. Users with self-edit permissions could modify notes of other users, including administrators, potentially leading to data integrity issues or unauthorized access to privileged information.

Compliance Impact

This vulnerability could impact compliance by allowing unauthorized modifications to user data, which may violate integrity requirements in GDPR (Article 5) and HIPAA (Security Rule). Unauthorized changes to sensitive metadata could lead to non-compliance with data protection and audit requirements.

Mitigation Strategies

Immediately upgrade Dolibarr to version 23.0.4 or 24.0.0. Apply the patch from commit 9b5229ef3a9b58d00252d327936b022fb739f149. Ensure server-side authorization checks are enforced to validate that the ID parameter matches the logged-in user unless explicit permissions exist.
