Dear Shop Operators,
In the digital commerce world, the security of your online shop is of paramount importance. A recently discovered critical security vulnerability, known as the “Magento Menu Bar Hack” (CVE-2025-47110), has demonstrated how crucial it is to keep your systems up to date. This vulnerability affects Adobe Commerce (Magento) platforms and can have devastating consequences for your shop and your customers.
What is the Magento Menu Bar Hack?
This attack uses a combination of cache poisoning and stored XSS (Cross-Site Scripting) to overwrite the admin menu bar of your Magento backend with malicious code. Attackers can thus take control of admin sessions and gain access to sensitive data, including customer data, payment flows, and even the ability to execute code on your server. A noticeable, temporary absence or malfunction of the dashboard menu bar for admin users can be an indicator of such an attack.
Why is this so critical?
Taking control of the admin account means that attackers gain full access to the innermost areas of your shop. This can lead to data leaks, financial losses, and a massive loss of trust among your customers. A quick response to such threats is crucial to prevent greater damage.
Your most urgent action: Update your shop!
Adobe has promptly released security updates and urges all shop operators to patch their platforms within 72 hours. The vulnerable versions include 2.4.8, 2.4.7-p5 and earlier, 2.4.6-p10 and earlier, 2.4.5-p12 and earlier, as well as 2.4.4-p13 and earlier versions of Magento and Adobe Commerce.
It is essential that you update your shop to the latest, secure versions. These include, for example:
- Magento 2.4.6-p11
- Magento 2.4.7-p6
- Magento 2.4.8-p1
In these patched versions, the security problem described above is fixed. As a professional Magento developer, we always emphasize the importance of regular updates, but with critical security vulnerabilities like this, quick action is absolutely necessary.
Protective measures and recommendations
In addition to the immediate updates, it is advisable to implement proactive defense measures. This includes regularly checking your system for anomalies and using security solutions that offer active protection.
