Summary

CVE-2026-23500 is a critical-severity OS Command Injection (CWE-78) vulnerability in Dolibarr Dolibarr Erp\/Crm. Its CVSS base score is 9.4 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 43% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-23500 is an OS command injection vulnerability (CWE-78) in Dolibarr, an open-source enterprise resource planning (ERP) and customer relationship management (CRM) software package. The issue affects versions prior to 23.0.0 and resides in the ODT to PDF conversion process within the odf.php file. Specifically, the MAIN_ODT_AS_PDF configuration constant is concatenated directly into a shell command passed to the exec() function without proper sanitization, enabling command injection.

An authenticated administrator can exploit this vulnerability by injecting arbitrary OS commands into the MAIN_ODT_AS_PDF constant using command separators. Exploitation occurs when any ODT template is generated, resulting in remote code execution (RCE) with the privileges of the web server user. The vulnerability has a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H), indicating high severity due to its network accessibility, low complexity, and potential for complete system compromise.

The Dolibarr security advisory (GHSA-w5j3-8fcr-h87w) and release notes for version 23.0.0 confirm that the issue has been addressed in that update, recommending immediate upgrades for affected installations. Practitioners should verify configurations and audit any custom MAIN_ODT_AS_PDF settings prior to patching.

Vulnerability Data

Dolibarr is an enterprise resource planning (ERP) and customer relationship management (CRM) software package. In versions prior to 23.0.0 , the ODT to PDF conversion process in odf.php concatenates the MAIN_ODT_AS_PDF configuration constant directly into a shell command passed to…

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
