Vulnerability Allowing MFA Bypass Affected EC-CUBE Versions Versions: 4.1.0 – 4.3.1 Vulnerability Overview If an administrator’s ID and password are compromised, an issue exists that allows an attacker to bypass the normally required two-factor authentication (2FA) and log in to the administrative interface. Severity and Impact CVSS v3.1 score Base score: 6.2 / Temporal score: 5.7 / Environmental score (after mitigation and countermeasures): 0.0 An attacker can forcibly overwrite the 2FA configuration of an account with administrative privileges. As a result, the legitimate administrator can be locked out, while the attacker can log in to the administrative interface and perform unauthorized actions such as viewing sensitive information or tampering with the website. Root Cause Details There are flaws in the access control implementation for the 2FA settings page (/admin/twofactorauth/set). 1.

# Patch Next advisory brief: GHSA-7rhv-h82h-vpjh

Advisory: EC-CUBE has a Vulnerability that Allows MFA Bypass in the Administrative Interface
IDs: GHSA-7rhv-h82h-vpjh
Record: https://patchnext.com/advisories/ghsa-7rhv-h82h-vpjh (revision 1, source checked 26 Oct 2026, 14:38 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist ec-cube/ec-cube: affected >= 4.1.0, <= 4.3.1

## Suggested inspection (read-only)
- Packagist ec-cube/ec-cube: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on ec-cube/ec-cube.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-7rhv-h82h-vpjh (GitHub-reviewed advisory GHSA-7rhv-h82h-vpjh lists affected ranges: Packagist ec-cube/ec-cube >=4.1.0 <=4.3.1)
