High-Risk Security Flaw Found in Dolibarr Software

A serious security weakness has been found in Dolibarr, a popular business management software. This flaw could let someone with access to the system run harmful code, potentially causing damage or stealing information. Small organisations using Dolibarr should take steps to protect themselves.

18 May 2026

Reference: CVE-2023-30253

1. What is being reported?

The report highlights a vulnerability in Dolibarr versions before 17.0.1. It allows a user who can log in to the system to execute harmful commands by exploiting a specific way the software handles certain code. This could let attackers take control or disrupt the system.

2. What this means in plain English

If someone with access to your Dolibarr system knows about this flaw, they could use it to cause serious problems, such as stealing data or damaging your software. This risk is higher if the software is not updated and if user access is not tightly controlled.

3. Could this affect a small business?

Small businesses or organisations using Dolibarr versions older than 17.0.1 could be affected, especially if multiple people have login access. Those not using Dolibarr or already updated to the latest version are unlikely to be impacted.

4. What to do now

  • Check which version of Dolibarr your organisation is using.
  • If using a version older than 17.0.1, arrange to update to the latest version as soon as possible.
  • Limit user access to Dolibarr only to trusted staff and review user permissions regularly.
  • Ask your IT provider to verify that your Dolibarr installation is secure and up to date.

5. Ask your IT provider

Can you confirm if our Dolibarr software is updated beyond version 17.0.1 and protected against the recent remote code execution vulnerability?

6. Bottom line

Keep your Dolibarr software updated and control user access to prevent serious security risks.
