    Published: 4 Nov 2026Last Modified: 7 Nov 2026

    Summary: DataGerry < 3.3.0 SSTI via DocAPI Template Rendering

    Details: DataGerry before 3.3.0 contains a server-side template injection vulnerability that allows authenticated attackers with base.docapi.template.add permission to store arbitrary Jinja2 payloads in the template_data field via POST /rest/docapi/template, which is later rendered in a non-sandboxed Jinja2 environment when a user calls GET /rest/docapi/template/<id>/render/<object_id>. Attackers can exploit the standard cycler.__init__.__globals__.os gadget chain to execute arbitrary operating system commands as the DataGerry web process user, confirmed as root in default Docker deployments, achieving remote code execution.
