CVE-2026-47999
Summary
by MITRE • 07/14/2026
Adobe Commerce is affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a high-privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim's browser when they browse to the page containing the vulnerable field. Scope is changed.

This vulnerability represents a critical stored cross-site scripting flaw in Adobe Commerce systems that enables high-privileged attackers to embed malicious javascript code within application form fields. The security weakness allows unauthorized users with elevated privileges to inject persistent script payloads that remain stored within the application's database or storage mechanisms. When legitimate users subsequently access pages containing these compromised fields, their browsers execute the malicious scripts within the context of their active sessions, creating significant attack surface opportunities for threat actors.
The technical implementation of this vulnerability stems from inadequate input validation and output sanitization mechanisms within Adobe Commerce's data handling processes. Specifically, the application fails to properly encode or escape user-supplied content before rendering it in web pages, creating conditions where attacker-controlled javascript can be seamlessly integrated into form fields and subsequently executed. This stored nature means that the malicious payload persists across multiple user sessions and page views until manually removed by administrators, fundamentally differentiating it from reflected XSS vulnerabilities that require specific user interactions to trigger.
From an operational impact perspective, this vulnerability enables sophisticated attack scenarios including session hijacking, credential theft, data exfiltration, and privilege escalation within the affected commerce platform. The high-privileged attacker profile suggests that threat actors could leverage compromised administrative accounts or elevated permissions to inject scripts that compromise entire user sessions. Attackers might exploit this weakness to steal customer data, manipulate order processing, access sensitive backend systems, or redirect users to malicious domains for phishing campaigns. The scope change indicates potential expansion beyond initial attack vectors, possibly affecting additional components within the Adobe Commerce ecosystem.
Organizations should implement comprehensive mitigation strategies including immediate patching of affected Adobe Commerce versions, deployment of web application firewalls with XSS detection capabilities, and implementation of robust input validation controls. The vulnerability aligns with CWE-79 (Cross-site Scripting) and maps to ATT&CK techniques such as T1566.001 (Phishing) and T1071.001 (Application Layer Protocol: Web Protocols). Additional protective measures include enforcing strict content security policies, implementing proper output encoding for all user-generated content, conducting regular security code reviews, and establishing monitoring procedures to detect anomalous script injection attempts within application forms and data entry points.
