CVE-2026-7294: Pizzafy Ecommerce System XSS Vulnerability

CVE-2026-7294 Overview

CVE-2026-7294 is a stored cross-site scripting (XSS) vulnerability in SourceCodester Pizzafy Ecommerce System 1.0. The flaw resides in the save_settings function exposed through /admin/index.php?page=save_settings. An authenticated administrator submitting a crafted Name parameter can inject JavaScript that executes in the context of users who later view the configuration page.

The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). The exploit has been published in public references, but exploitation requires high privileges and user interaction, limiting practical impact.

Critical Impact

Authenticated attackers can inject persistent JavaScript into the admin settings page, enabling session theft or unauthorized actions against other administrators.

Affected Products

• SourceCodester Pizzafy Ecommerce System 1.0
• /admin/index.php?page=save_settings endpoint
• save_settings function handling the Name parameter

Technical Details for CVE-2026-7294

Vulnerability Analysis

The vulnerability is a stored cross-site scripting flaw in the administrative settings handler of Pizzafy Ecommerce System 1.0. The save_settings function processes form data submitted to /admin/index.php?page=save_settings without applying output encoding or input sanitization to the Name argument. Injected payloads persist in the application's configuration store and execute whenever an administrator renders the settings view.

Because the affected endpoint sits behind administrative authentication, exploitation depends on either an existing privileged session or a secondary vector that places malicious values into the configuration. The published proof-of-concept demonstrates payload persistence and reflection without additional protective controls in place.

Root Cause

The root cause is missing input validation and output encoding in the save_settings workflow. User-supplied content from the Name parameter is stored verbatim and emitted into HTML responses without contextual escaping, satisfying the conditions described in CWE-79.

Attack Vector

The attack vector is network-based and requires high privileges plus user interaction. An attacker with administrator access submits a Name value containing JavaScript through the settings form. The payload is rendered without escaping when any administrator subsequently loads the settings page, executing script in the victim's browser session. Refer to the GitHub XSS Report PDF and VulDB Vulnerability #359954 for technical details of the published proof-of-concept.

Detection Methods for CVE-2026-7294

Indicators of Compromise

• HTTP POST requests to /admin/index.php?page=save_settings containing HTML or JavaScript syntax such as <script>, onerror=, or javascript: in the Name parameter.
• Stored configuration values in the Pizzafy database that include encoded or raw script tags.
• Outbound requests from administrator browsers to unfamiliar domains shortly after loading the settings page.

Detection Strategies

• Inspect web server access logs for POST traffic to the save_settings page and flag bodies containing tag delimiters or event handler attributes.
• Deploy Web Application Firewall (WAF) signatures that detect XSS payloads on admin endpoints of PHP applications.
• Run periodic database audits on configuration tables to identify stored HTML or script content in administrative fields.

Monitoring Recommendations

• Alert on anomalous administrator session activity that follows visits to /admin/index.php?page=save_settings.
• Monitor browser-reported Content Security Policy (CSP) violations from administrative pages.
• Correlate admin authentication events with subsequent configuration writes to detect compromised credentials being used to plant payloads.

How to Mitigate CVE-2026-7294

Immediate Actions Required

• Restrict access to /admin/index.php?page=save_settings to trusted networks and enforce strong administrator authentication.
• Audit existing settings values for stored HTML or JavaScript content and remove any unexpected entries.
• Rotate administrator credentials and invalidate active sessions if tampering is suspected.

Patch Information

No official vendor patch is currently referenced in the CVE record. Operators should monitor the SourceCodester Security Resources page and the VulDB Vulnerability #359954 entry for updates. Until a fix is released, apply the workarounds below.

Workarounds

• Apply server-side input validation on the Name parameter, rejecting any value containing <, >, or quote characters used for HTML attribute breaking.
• Implement HTML entity encoding using htmlspecialchars($value, ENT_QUOTES, 'UTF-8') before emitting stored settings into pages.
• Enforce a strict Content Security Policy on administrative pages that disables inline scripts and limits script sources to trusted origins.
• Place the application behind a WAF with XSS detection rules enabled for /admin/ paths.

# Example CSP header to mitigate stored XSS on admin pages
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'"
