Summary A SQL Injection vulnerability exists in the Third Party (Company) update functionality of Dolibarr ERP/CRM. The `localtax1_value` parameter (`lt1`) is concatenated directly into an SQL UPDATE statement in `societe/class/societe.class.php` at line 1672 without any escaping, type casting, or parameterized query binding. An authenticated user with standard "Third Party: Create/Edit" permission can extract any data from the database, including password hashes, API keys, and all business data. Tested on Dolibarr v23.0.0 (latest stable), default installation via official Docker image, MariaDB 10.11. No custom modules, no modified configuration.

Details Vulnerable code (`societe/class/societe.class.php`, line 1672): ```php $sql .= ",localtax1_value =".$this->localtax1_value; ``` The value comes from `GETPOST('lt1', 'alpha')` (`societe/card.php`, line 1135). The only sanitization applied is `trim()` at line 1528 — no `(float)` cast, no `$db->escape()`. The `alpha` input…

# Patch Next advisory brief: CVE-2026-33944

Advisory: Dolibarr has SQL Injection in societe/class/societe.class.php via localtax1_value parameter
IDs: CVE-2026-33944, GHSA-v5fq-cf5m-vwv7
Record: https://patchnext.com/advisories/cve-2026-33944 (revision 2, source checked 28 Oct 2026, 06:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
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 <= 23.0.0

## 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.
