What is CVE-2026-76201?

Adobe Commerce has a vulnerability that may allow attackers to conduct stored Cross-Site Scripting (XSS) attacks. By exploiting this flaw, an attacker can inject harmful scripts into vulnerable form fields. When a user subsequently accesses the affected page, the malicious JavaScript executes in the victim's browser. This can lead to unauthorized access and control over the victim's session or account, resulting in potential data theft or manipulation. Ensuring that affected products are updated and secure is critical to preventing such security breaches.
