Executive Summary

CVE-2026-71506 is an improper authorization flaw in Dolibarr, an open-source ERP and CRM system. The vulnerability exists in the payments REST API delete endpoint where the system incorrectly checks for invoice-deletion rights instead of payment-specific rights. This allows authenticated users with limited privileges to delete payment records they should not have access to, potentially altering financial data integrity.

Detection Guidance

To detect this vulnerability, check Dolibarr versions prior to 24.0.0 by running: grep -r 'version' /path/to/dolibarr/installation. Look for unauthorized payment deletions in logs by searching for DELETE requests to /api/paiements endpoint in web server logs.

Impact Analysis

This vulnerability allows attackers to permanently delete payment records, zero out paid amounts on invoices, and remove entries from accounting exports. This can lead to financial discrepancies, inflated outstanding balances, customer disputes, and disrupted accounting records. Organizations using affected Dolibarr versions may face financial losses and compliance issues.

Compliance Impact

This vulnerability can lead to violations of GDPR and HIPAA by compromising financial data integrity. GDPR requires accurate record-keeping and protection of personal data, while HIPAA mandates secure handling of financial records in healthcare. Unauthorized deletion of payment records may result in non-compliance, potential fines, and loss of trust in data management practices.

Mitigation Strategies

Immediately upgrade Dolibarr to version 24.0.0 or later. Review user permissions to ensure only authorized users have invoice-deletion rights. Monitor accounting exports for missing payment records and verify financial data integrity.
