CVE-2026-108828: Zen Cart admin panel remote code execution via eval injection

CVE-2026-108828 · Severity: medium · CVSS 4.1 · Published 2026-10-12

Zen Cart is an e-commerce platform that manages online store configuration through an admin panel. A vulnerability in the admin configuration page allows remote code execution when an attacker can modify database entries, potentially leading to full server compromise, data theft, or store defacement. The attack requires admin panel access and a separate database injection vector, but once exploited grants the attacker complete control with web server privileges.

Technologies: Zen Cart. Vendors: Zen Cart.

Quick answers

Is CVE-2026-108828 exploited in the wild?
No. Junglewise Threat Intelligence has no report of CVE-2026-108828 being exploited in the wild.
How severe is CVE-2026-108828?
Medium severity, with a CVSS score of 4.1, published 12 October 2026.
Which products and versions are affected?
Zen Cart 2.2.2.
Is there a fix for CVE-2026-108828?
No fixed version is recorded yet. Restrict database access and disable direct administrative SQL execution. Review and validate all configuration entries in the database, particularly set_function and use_function fields, ensuring they contain only legitimate function calls. Apply the principle of least privilege to the database user account that the application uses. If you run it, Junglewise drafts a mitigation that fits your setup and applies it once you approve, with senior security engineers behind it.
How is CVE-2026-108828 attacked?
It is attacked over the network.
Am I affected by CVE-2026-108828?
Check whether you run Zen Cart at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

How to fix

Restrict database access and disable direct administrative SQL execution. Review and validate all configuration entries in the database, particularly set_function and use_function fields, ensuring they contain only legitimate function calls. Apply the principle of least privilege to the database user account that the application uses.

Technical details

The admin/configuration.php file unsafely passes database-stored configuration values directly to PHP's eval() function without sanitization. An attacker who can inject SQL (via a separate vulnerability) can modify the set_function database field to contain malicious PHP code, which executes when an administrator accesses the configuration page. Successful exploitation yields arbitrary code execution with web server privileges.
