CVE-2026-14800 Overview
CVE-2026-14800 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the imhamzaazam/ecommerceFlask open-source project up to commit cb7d9e24c30a99379651b7493b32048126ef402b. The flaw resides in an unspecified function that fails to validate the origin or authenticity of state-changing HTTP requests. Because the project follows a rolling release model, no discrete version identifiers are published for affected or fixed builds. A public exploit for this issue has been disclosed, and the maintainer has not yet responded to the reporter's issue.
Critical Impact
A remote attacker can trick an authenticated user into submitting forged requests, resulting in unauthorized state changes within the ecommerceFlask application.
Affected Products
- imhamzaazam/ecommerceFlask up to commit cb7d9e24c30a99379651b7493b32048126ef402b
- All rolling-release builds prior to a maintainer-provided fix
- Deployments exposing the application to untrusted browser sessions

Technical Details for CVE-2026-14800
Vulnerability Analysis
The vulnerability is classified as Cross-Site Request Forgery under [CWE-352]. The ecommerceFlask application accepts authenticated state-changing HTTP requests without verifying that the request originated from a trusted context. An attacker who can lure an authenticated user to a malicious page can cause that user's browser to submit an attacker-crafted request to the application. The request executes with the victim's session credentials, allowing unauthorized actions on the victim's behalf.
The issue affects request confidentiality and integrity boundaries within the web layer. Because Flask applications commonly rely on cookie-based sessions, absence of anti-CSRF tokens or SameSite protections leaves endpoints exposed to forged submissions.
Root Cause
The root cause is the absence of anti-CSRF controls on state-changing endpoints. The application does not implement synchronizer tokens, double-submit cookies, or origin/referer validation. Extensions such as Flask-WTF CSRF protection appear to be either absent or misconfigured across the vulnerable routes.
Attack Vector
Exploitation is remote and requires user interaction. The attacker hosts a malicious page containing an auto-submitting HTML form or an image tag that references a state-changing endpoint of the target application. When an authenticated victim visits the page, the browser attaches the session cookie and issues the forged request. The application processes the request as legitimate. Refer to the VulDB Vulnerability Report for additional exploitation context.
The vulnerability manifests when routes handling account modifications, cart operations, or order submissions accept POST requests without token validation. No verified exploit code is included here; consult the GitHub Issue Tracker for reporter details.
Detection Methods for CVE-2026-14800
Indicators of Compromise
- Unexpected state changes on user accounts (address updates, password resets, order placements) not initiated by the user.
- HTTP POST requests to sensitive endpoints containing Referer or Origin headers pointing to untrusted third-party domains.
- Anomalous clusters of identical POST requests originating from multiple authenticated sessions in short time windows.
Detection Strategies
- Inspect web server access logs for state-changing requests lacking a same-origin Referer header.
- Deploy a Web Application Firewall (WAF) rule set that flags POST requests missing anti-CSRF tokens on sensitive routes.
- Correlate authentication session identifiers against request origin headers to surface cross-origin submissions.
Monitoring Recommendations
- Enable verbose request logging for all POST, PUT, and DELETE endpoints in the ecommerceFlask deployment.
- Alert on requests where Origin or Referer does not match the application's canonical hostname.
- Track user complaints about unauthorized account or order changes as a leading indicator of exploitation attempts.
How to Mitigate CVE-2026-14800
Immediate Actions Required
- Restrict public exposure of the ecommerceFlask application until CSRF protections are in place.
- Configure session cookies with SameSite=Lax or SameSite=Strict and the Secure flag to reduce cross-site submission risk.
- Integrate Flask-WTF CSRF protection and require tokens on every state-changing route.
- Validate Origin and Referer headers on the server side for all POST, PUT, PATCH, and DELETE requests.
Patch Information
No official patch has been published. The maintainer of the GitHub Project Repository has not responded to the disclosure filed in the GitHub Issue Tracker. Consumers of the rolling release must apply mitigations manually or fork the project to implement CSRF defenses. Track the VulDB CVE Entry for status updates.
Workarounds
- Enable a reverse proxy or WAF rule that rejects state-changing requests missing a same-origin Referer header.
- Add Flask-WTF and wrap the application with CSRFProtect(app) to enforce token validation globally.
- Set session cookies to SameSite=Strict in the Flask configuration to block cross-site cookie transmission.
- Require re-authentication for high-impact actions such as password changes or order confirmations.
# Configuration example
pip install Flask-WTF
# In app.py
# from flask_wtf.csrf import CSRFProtect
# app.config['SESSION_COOKIE_SAMESITE'] = 'Strict'
# app.config['SESSION_COOKIE_SECURE'] = True
# app.config['WTF_CSRF_TIME_LIMIT'] = 3600
# csrf = CSRFProtect(app)
