CVE-2026-7689
LowCVSS 3.7Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
Summary
A security flaw was discovered in Dolibarr ERP CRM up to 23.0.2 in the dol_verifyHash function of htdocs/core/lib/security.lib.php within the Online Signature Module. Manipulation results in improper verification of cryptographic signature. The attack may be performed remotely but is highly complex and difficult to exploit; the exploit has been released publicly and the vendor did not respond.
Risk Assessment
Improper cryptographic signature verification may allow bypassing electronic signature security mechanisms, potentially leading to document forgery. Public exploit availability increases the risk.
Recommendation
Update Dolibarr to a patched version as soon as available and monitor the vendor's status. Until patched, limit use of the online signature module.
Other vulnerabilities in Dolibarr ERP CRM
See all- CVE-2026-116218High
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.
- CVE-2026-37713High
An issue in Dolibarr ERP/CRM versions 22.0.0 through 22.0.4 and 24.0.0-alpha allows a remote attacker to execute arbitrary code via the htdocs/core/class/commonobject.class.php.
- CVE-2026-37712High
An issue in Dolibarr ERP/CRM versions 22.0.0 through 22.0.4 and 24.0.0-alpha allows a remote attacker to execute arbitrary code via the htdocs/cron/class/cronjob.class.php, in the call_user_func_array() function.
- CVE-2026-37711High
An issue in Dolibarr ERP/CRM versions 22.0.0 through 22.0.4 and 24.0.0-alpha allows a remote attacker to execute arbitrary code via the htdocs/core/actions_addupdatedelete.inc.php.
- CVE-2017-17898High
Dolibarr ERP/CRM version 6.0.4 does not block direct requests to *.tpl.php files, allowing remote attackers to obtain sensitive information.
- CVE-2017-9840High
Dolibarr ERP/CRM version 5.0.3 and prior allows low-privilege users to upload files of dangerous types, which can result in arbitrary code execution within the context of the vulnerable application.
- CVE-2018-25357Critical
Dolibarr ERP CRM 7.0.3 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary code by injecting PHP code through the db_name parameter. Attackers can send a POST request to install/step1.php with malicious PHP code in the db_name parameter, then execute commands via the check.php endpoint using the cmd GET parameter.
- CVE-2026-23500Critical
Dolibarr is an enterprise resource planning (ERP) and customer relationship management (CRM) software package. In versions prior to 23.0.0, the ODT to PDF conversion process in odf.php concatenates the MAIN_ODT_AS_PDF configuration constant directly into a shell command passed to exec() without sanitization.
- CVE-2026-22666High
A vulnerability in Dolibarr ERP/CRM prior to version 23.0.2 allows authenticated attackers with administrator privileges to achieve remote code execution. The issue is in the dol_eval_standard() function, which fails to apply forbidden string checks in whitelist mode and does not detect PHP dynamic callable syntax.
- CVE-2023-38888Critical
A Cross Site Scripting (XSS) vulnerability in Dolibarr ERP CRM version 17.0.1 and earlier allows a remote attacker to obtain sensitive information and execute arbitrary code via the REST API module, related to analyseVarsForSqlAndScriptsInjection and testSqlAndScriptInject functions.
Original NVD description (English source)
A security flaw has been discovered in Dolibarr ERP CRM up to 23.0.2. This vulnerability affects the function dol_verifyHash in the library htdocs/core/lib/security.lib.php of the component Online Signature Module. The manipulation results in improper verification of cryptographic signature. The attack may be performed from remote. Attacks of this nature are highly complex. It is stated that the exploitability is difficult. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
