CVE-2026-111552: Hyper E-Commerce: single-factor auth allows bypass

HIGH

Published November 12, 2026

CISO Take

This is a single-factor authentication weakness (CWE-308) in Hyper Teknoloji's Hyper E-Commerce Infrastructure, its dealer integration module and its storefront and management panel. It allows authentication bypass over the network with low complexity and low privileges. Nothing in the data ties it to an AI/ML component, so the 'ml_ui' category looks like a misclassification and the AI-specific blast radius is minimal. Urgency is moderate: the CVSS is 7.1 (high confidentiality impact), but there is no public exploit, no Nuclei template, no CISA KEV listing and no EPSS score. Upgrade to Hyper E-Commerce Infrastructure 1.1, dealer integration 1.2 and storefront/management panel 2.1796 or later, and add MFA to management and dealer interfaces. Also confirm whether any AI tooling, such as recommendation or chatbot services, integrates with these platforms.

What is the risk?

Rated high by CVSS 3.1 (7.1): network-reachable, low complexity, low privileges, no user interaction, high confidentiality impact, low integrity impact. Exploitation likelihood is unquantified because EPSS is N/A. There is no public exploit, scanner template or KEV listing. The AI/ML-specific risk is low, because the product is an e-commerce platform and no AI package is identified. Organizations running this software face conventional risk to customer, dealer and order data. Any AI features that consume its data are exposed only indirectly.

How does the attack unfold?

Initial Access

The attacker reaches the exposed management panel or dealer integration endpoint over the network with low-privilege credentials.

AML.T0049

Authentication Bypass

The attacker exploits the single-factor authentication flaw (CWE-308) to gain access beyond their privilege level.

AML.T0012

Impact

The attacker reads sensitive customer, order and dealer data and makes limited modifications, which may also affect any downstream ML pipelines.

What should I do?

6 steps

Upgrade Hyper E-Commerce Infrastructure to 1.1 or later, dealer integration to 1.2 or later, and the storefront/management panel to 2.1796 or later.
Until patched, restrict the management panel and dealer integration endpoints to trusted IP ranges, a VPN or an allowlist.
Enforce multi-factor authentication or a reverse-proxy authentication layer in front of administrative interfaces.
Review authentication logs for anomalous logins, session creation without a full credential flow, and unusual dealer-account activity.
Rotate dealer and administrator credentials and API keys if suspicious activity is found.
Follow the Turkish national CERT advisory (siberguvenlik.gov.tr, TR-26-1531) for vendor guidance.

Original Advisory

Use of single-factor authentication vulnerability in Hyper Teknoloji Ltd. Şti. Hyper E-Commerce Infrastructure, Hyper Teknoloji Ltd. Şti. Hyper E-Commerce Infrastructure - dealer integration, and Hyper Teknoloji Ltd. Şti. Hyper E-Commerce Infrastructure - Storefront application and management panel allows Authentication Bypass. This issue affects Hyper E-Commerce Infrastructure: before 1.1; Hyper E-Commerce Infrastructure - dealer integration: before 1.2; Hyper E-Commerce Infrastructure - Storefront application and management panel: before 2.1796.

Exploitation Scenario

An attacker with a low-privilege account, such as a dealer or a registered storefront user, targets an exposed management or dealer integration endpoint. Because the authentication relies on a single factor and is flawed, the attacker bypasses the check and reaches data or functions beyond their privileges. They read customer and order records and make limited changes to data. If an ML recommendation or forecasting pipeline consumes that data, the attacker could also skew its inputs. This is speculative, since no AI integration is documented.

Weaknesses (CWE)

CWE-308Use of Single-factor AuthenticationPrimary CWE-308Use of Single-factor Authentication

CWE-308 — Use of Single-factor Authentication: The product uses an authentication algorithm that uses a single factor (e.g., a password) in a security context that should require more than one factor.

[Architecture and Design] Use multiple independent authentication schemes, which ensures that -- if one of the methods is compromised -- the system itself is still likely safe from compromise. For this reason, if multiple schemes are possible, they should be implemented and required -- especially if they are easy to use.
