CVE-2026-16226: Pizzafy Ecommerce System RCE Vulnerability

CVE-2026-16226 Overview

CVE-2026-16226 is an unrestricted file upload vulnerability in SourceCodester Pizzafy Ecommerce System 1.0. The flaw resides in the save_settings function of /admin/admin_class_novo.php. Attackers can manipulate the img parameter to upload arbitrary files to the server. The vulnerability is exploitable remotely over the network, though it requires high privileges to trigger. The weakness is classified under [CWE-284] Improper Access Control. Successful exploitation can lead to persistent malicious content on the web server and undermine the integrity of the ecommerce application.

Critical Impact
Authenticated attackers can upload arbitrary files through the settings image parameter, potentially placing malicious content on the server and impacting confidentiality, integrity, and availability of the Pizzafy Ecommerce application.

Technical Details for CVE-2026-16226

Vulnerability Analysis

The vulnerability exists in the administrative settings handler of Pizzafy Ecommerce System 1.0. The save_settings function in /admin/admin_class_novo.php accepts an img argument used to store a settings image. The routine does not sufficiently restrict the type, extension, or content of uploaded files. As a result, an authenticated administrator or an attacker who has obtained privileged credentials can submit files that fall outside the intended image scope. Uploaded artifacts may then be written into a web-accessible directory. Because Pizzafy is a PHP application, files placed within the document root can be requested directly through the web server. The issue aligns with [CWE-284] Improper Access Control, reflecting missing enforcement on what may be written by the settings interface.

Root Cause

The root cause is missing validation of file uploads inside the save_settings handler. The img parameter is processed without robust checks for extension, MIME type, magic bytes, or destination path. This absence of controls constitutes an unrestricted upload weakness.

Attack Vector

The attack is network-based and targets the administrator interface of Pizzafy Ecommerce. An actor with valid privileged credentials submits a crafted multipart request to the settings endpoint. The malicious payload is delivered through the img field. No user interaction is required beyond the attacker's own authenticated request.

No verified proof-of-concept code is publicly available for this issue. Refer to the VulDB CVE-2026-16226 entry and VulDB Vulnerability #380048 for additional technical context.

Detection Methods for CVE-2026-16226

Indicators of Compromise

Unexpected files with executable extensions (.php, .phtml, .phar) inside directories used by the Pizzafy settings module.
HTTP POST requests to /admin/admin_class_novo.php referencing the save_settings action with non-image content in the img field.
New or modified files in the web root created shortly after administrator authentication events.

Detection Strategies

Inspect web server access logs for POST requests to admin_class_novo.php correlated with subsequent GET requests to newly created files.
Monitor file integrity within the Pizzafy web root to flag creation of non-image files by the PHP process user.
Alert on multipart uploads to the settings endpoint where the declared MIME type does not match the file magic bytes.

Monitoring Recommendations

Forward web server, PHP-FPM, and file system audit logs to a centralized analytics platform for correlation.
Track successful and failed administrator authentication attempts against the Pizzafy admin panel.
Baseline expected image formats in the settings directory and alert on deviations.

How to Mitigate CVE-2026-16226

Immediate Actions Required

Restrict network access to the Pizzafy /admin/ path to trusted management IP ranges only.
Rotate administrator credentials and enforce strong, unique passwords for privileged accounts.
Audit the web root for unauthorized files and remove any artifacts placed through the settings endpoint.

Patch Information

As of the last NVD update on 2026-07-20, no vendor patch has been referenced in the advisory materials. Consult the SourceCodester project page and the VulDB submission for any subsequent fix releases before deploying the application in production environments.

Workarounds

Implement a server-side allow-list of extensions (.jpg, .jpeg, .png, .gif) and validate magic bytes before writing files to disk.
Store uploads outside the web root or in a directory where PHP execution is disabled via web server configuration.
Place the admin interface behind an authenticated reverse proxy or VPN to reduce exposure of the vulnerable endpoint.

bash

# Example Apache configuration to disable PHP execution in upload directory
<Directory "/var/www/pizzafy/uploads">
    php_admin_flag engine off
    <FilesMatch "\.(php|phtml|phar)$">
        Require all denied
    </FilesMatch>
</Directory>
