CVE-2026-34036
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDolibarr is an enterprise resource planning (ERP) and customer relationship management (CRM) software package. In versions 22.0.4 and prior, there is a Local File Inclusion (LFI) vulnerability in the core AJAX endpoint /core/ajax/selectobject.php. By manipulating the objectdesc parameter and exploiting a fail-open logic flaw in the core access control function restrictedArea(), an authenticated user with no specific privileges can read the contents of arbitrary non-PHP files on the server (such as .env, .htaccess, configuration backups, or logs…). At time of publication, there are no publicly available patches.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisA PHP include or require path is built from user-controlled input, so an attacker can steer it to a remote URL or an unintended local file — and because the target is then executed as code, this often becomes remote code execution. It is the classic remote/local file-inclusion trap. The fix is never to build include paths from input: map requests to a fixed allow-list of includable files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedDolibarr 22.0.5 or later (any version > 22.0.4)
- 1. Back up your Dolibarr installation and database before upgrading.
- 2. Download Dolibarr version 22.0.5 or later from the official Dolibarr website (https://www.dolibarr.org) or GitHub releases.
- 3. Extract the new version files, preserving your custom configuration in the 'conf' directory.
- 4. Ensure the 'objectdesc' parameter is not directly used in file inclusion operations in /core/ajax/selectobject.php - the vendor patch at commit 743c22e57c0b2a017d6b92bec865d71ce6177a6a addresses this by adding proper input validation.
- 5. After upgrading, verify that the restrictedArea() function in core/accesscontrol.php properly validates and restricts access before allowing file operations.
- 6. Test the selectobject.php endpoint with a non-privileged authenticated user to confirm the LFI is no longer exploitable.
- 7. Review .env, configuration, and other sensitive files to ensure they have not been compromised.
