CVE-2026-116218 in Dolibarr
Summary
by MITRE • 10/26/2026
Dolibarr ERP CRM 19.0.0 before 23.0.4 contains an SQL injection vulnerability that allows authenticated API users to inject SQL via the type field of the third-party bankaccounts REST endpoint. Attackers with only societe/creer permission can break out of the unescaped type value in CompanyBankAccount::create() to read password hashes and API keys via time-based blind subqueries.

The vulnerability identified in Dolibarr ERP CRM versions prior to 23.0.4 represents a critical security flaw within its RESTful application programming interface, specifically targeting the third-party bank accounts endpoint. This SQL injection issue arises from improper input validation and sanitization mechanisms when processing data submitted through API requests. The core of the problem lies in how the system handles the type field associated with company bank account creation or modification operations. Despite being an authenticated vulnerability requiring initial access to the application, this flaw allows attackers who possess only basic permissions such as societe/creer to execute arbitrary SQL commands against the underlying database infrastructure.
From a technical perspective, the root cause is traced directly to the CompanyBankAccount::create() method within the Dolibarr codebase. When an authenticated user submits data via the REST endpoint, the application fails to properly escape or parameterize the type field before incorporating it into dynamic SQL queries. This lack of proper input handling allows malicious actors to break out of the intended string context and inject additional SQL syntax. The vulnerability is particularly insidious because it does not rely on immediate error-based feedback but rather facilitates time-based blind subqueries. This technique involves crafting payloads that cause measurable delays in database response times, allowing attackers to infer data character by character without triggering obvious errors or alerts that might otherwise indicate an attack attempt.
The operational impact of this vulnerability is severe due to the sensitive nature of the data accessible through exploitation. By leveraging time-based blind SQL injection techniques, adversaries can extract critical authentication credentials stored within the database, including password hashes and API keys. The extraction of password hashes enables offline brute-force attacks against user accounts, potentially leading to privilege escalation if weak hashing algorithms are in use or if users reuse passwords across different systems. Furthermore, the theft of API keys compromises the integrity and confidentiality of automated integrations connected to the Dolibarr instance, allowing attackers to impersonate legitimate services or exfiltrate additional business-critical data through authorized channels.
This vulnerability aligns with CWE-89 Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection. The exploitation method described corresponds closely to ATT&CK technique T1059.004 SQL Commands for Data Extraction and potentially T1078 Valid Accounts if the attacker leverages stolen credentials or API keys to maintain persistent access. The fact that it requires only societe/creer permission highlights a significant issue with role-based access control granularity, where low-privilege users are granted sufficient rights to interact with sensitive endpoints without adequate input validation safeguards.
Mitigation strategies must prioritize immediate patching of the Dolibarr ERP CRM software to version 23.0.4 or later, which addresses this specific flaw by implementing proper parameterized queries and enhanced input sanitization for all API endpoints handling bank account data. In environments where upgrading is not immediately feasible, network-level controls such as Web Application Firewalls should be configured to detect and block SQL injection patterns in RESTful traffic, particularly within POST requests targeting the third-party bank accounts endpoint. Additionally, organizations should enforce strict least-privilege principles by reviewing API key permissions and ensuring that database users operating under Dolibarr have minimal necessary privileges, thereby limiting the potential blast radius of any successful exploitation attempt. Regular security audits focusing on input validation across all public-facing APIs are essential to prevent similar vulnerabilities from persisting in future releases or custom modules.
