• CVE-2026-23500: 0.92% estimated exploitation activity in the next 30 days; percentile 60.37 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary An authenticated administrator can execute arbitrary operating system commands by injecting a malicious payload into the MAINODTASPDF configuration constant. This vulnerability exists because the application fails to properly validate or escape the command path before passing it to the exec() function in the ODT to PDF conversion process. Details The vulnerability is located in htdocs/includes/odtphp/odf.php. When the system tries to convert an ODT document to PDF (e.g., in Proposals, Invoices), it constructs a shell command using the MAINODTASPDF global setting. Code snippet (htdocs/includes/odtphp/odf.php, approx line 930): While the filename $name is sanitized using escapeshellcmd(), the configuration variable MAINODTASPDF is retrieved directly from the database and concatenated at the beginning of the string. An attacker with administrative privileges can set this variable to include a command separator (like ;) followed by arbitrary commands. PoC Prerequisites: 1. Login…

# Patch Next advisory brief: CVE-2026-23500

Advisory: Dolibarr: OS Command Injection (RCE) via MAIN_ODT_AS_PDF configuration
IDs: CVE-2026-23500, GHSA-w5j3-8fcr-h87w
Record: https://patchnext.com/advisories/cve-2026-23500 (revision 1, source checked 26 Oct 2026, 14:40 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist dolibarr/dolibarr: affected <= 22.0.4

## Suggested inspection (read-only)
- Packagist dolibarr/dolibarr: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on dolibarr/dolibarr.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-w5j3-8fcr-h87w (GitHub-reviewed advisory GHSA-w5j3-8fcr-h87w lists affected ranges: Packagist dolibarr/dolibarr >=0 <=22.0.4)
