Security readout for executives and security teams
Plain-English summary
CVE-2026-31019 affects Dolibarr ERP & CRM’s Website module in versions 22.0.4 and below. A logged-in user who can edit PHP content may bypass safety filtering and run operating system commands on the server. This is high business risk where untrusted or broadly assigned content-editing permissions exist.
Executive priority
Prioritize within the next remediation cycle, faster for internet-facing or multi-user Dolibarr environments. The key business concern is that a compromised or overprivileged account could lead to full server takeover, data theft, disruption, or lateral movement.
Technical view
The issue is a CWE-78 command injection / OS command execution flaw. Dolibarr uses blacklist-based filtering for dangerous PHP functions, but an authenticated low-privilege path with PHP edit permission can bypass it. CVSS is 8.8, network exploitable, low complexity, privileges required, no user interaction, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely in Dolibarr ERP & CRM 22.0.4 and below with the Website module enabled and users granted permission to edit PHP content. Internet-facing Dolibarr instances increase impact, but exploitation still requires authenticated access with the relevant permission.
Exploitation context
The provided sources do not show CISA KEV listing or confirm active exploitation. The public reference appears to describe the vulnerability, but defenders should treat it seriously because successful exploitation can become full server-side remote code execution.
Researcher notes
Evidence is limited to the CVE record and a public GitHub reference. The affected-product metadata is sparse, but the description clearly names Dolibarr ERP & CRM 22.0.4 and below. No official vendor advisory or patch details were included in the provided bundle.
Mitigation direction
- Check Dolibarr vendor guidance for the fixed version or official workaround.
- Upgrade Dolibarr according to vendor instructions when a fix is available.
- Remove PHP content editing permission from non-essential users immediately.
- Restrict Dolibarr administrative access to trusted networks where possible.
- Review Website module usage and disable risky editing features if not needed.
Validation and detection
- Inventory Dolibarr instances and confirm versions are 22.0.4 or below.
- Identify whether the Website module is enabled.
- List accounts with permission to edit PHP content.
- Review recent Website module content changes for unauthorized modifications.
- Check application and server logs for suspicious command-execution indicators.

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
