CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2026-22666 impacting dolibarr dolibarr_erp\/crm. Evaluated with CVSS Base Score of 7.2 (HIGH).

Original NVD Description

Source: NIST NVD
Dolibarr ERP/CRM versions prior to 23.0.2 contain an authenticated remote code execution vulnerability in the dol_eval_standard() function that fails to apply forbidden string checks in whitelist mode and does not detect PHP dynamic callable syntax. Attackers with administrator privileges can inject malicious payloads through computed extrafields or other evaluation paths using PHP dynamic callable syntax to bypass validation and achieve arbitrary command execution via eval().
