How to Fix CVE-2026-31019

To remediate this vulnerability, upgrade all affected Dolibarr/dolibarr dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dolibarr/dolibarr fixed: Latest secure release 
Upgrade dolibarr/dolibarr to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for dolibarr/dolibarr

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-31019, inspect your project dependencies for Dolibarr/dolibarr:

inspect dependencies for dolibarr/dolibarr

Analyze the terminal output to locate any version of Dolibarr/dolibarr in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Dolibarr/dolibarr, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the Website module of Dolibarr ERP & CRM 22.0.4 and below, the application uses blacklist-based filtering to restrict dangerous PHP functions related to system command execution. An authenticated user with permission to edit PHP content can bypass this filtering, resulting in full remote code execution with the ability to execute arbitrary operating system commands on the server.
