CVE-2026-29207 Apache Software Foundation CVE debrief
Apache OFBiz versions prior to 24.09.06 contain an improper neutralization of special elements used in a template engine (CWE-1336), allowing attackers to inject malicious content into FreeMarker templates. The vulnerability stems from insufficient sanitization of user-supplied input processed by the template engine, potentially enabling remote code execution or information disclosure depending on the application's configuration and permissions.

Who should care
Organizations running Apache OFBiz for ERP, e-commerce, or business process management; security teams responsible for Java application security; compliance officers tracking Apache Software Foundation product vulnerabilities; developers maintaining custom OFBiz integrations or themes using FreeMarker templates.
Technical summary
This vulnerability exists in Apache OFBiz's template processing subsystem where user-controllable input can reach the FreeMarker template engine without adequate sanitization. The attack vector is network-accessible with low attack complexity and no required privileges or user interaction. Successful exploitation could allow attackers to execute arbitrary code within the OFBiz application context or access sensitive information. The remediation in 24.09.06 removes FTL template support entirely and restricts content management permissions for the Ecommerce Customer role, indicating these features were primary exploitation pathways. Organizations must both patch and manually audit configurations due to the breaking permission changes not automatically applied during upgrade.
Defensive priority
high
Recommended defensive actions
- Upgrade Apache OFBiz to version 24.09.06 or later immediately
- Review and remove 'Data Resource' records with dataTemplateTypeId = 'FTL' as these are no longer supported
- Audit and remove content management grants from the 'Ecommerce Customer' security group in production environments
- Review application logs for suspicious template syntax or unexpected FreeMarker processing errors prior to 2026-05-19
- Implement input validation and output encoding for all user-supplied data processed by template engines
- Consider network segmentation to limit OFBiz administrative interfaces to trusted hosts only
Evidence notes
The vulnerability is classified under CWE-1336 (Improper Neutralization of Special Elements in a Template Engine). CVSS 3.1 vector: AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N. Affected versions: all Apache OFBiz versions before 24.09.06. The vendor advisory confirms exploitation through template injection in Data Resource records with dataTemplateTypeId = 'FTL'.
