CVE-2026-48413 in Commerce
Summary
by MITRE • 08/11/2026
Adobe Commerce is affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low-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, potentially gaining elevated access or control over the victim's account or session. Scope is changed.

This stored cross-site scripting vulnerability in Adobe Commerce represents a critical security flaw that allows low-privileged attackers to inject malicious JavaScript code into form fields within the application's user interface. The vulnerability stems from inadequate input validation and output encoding mechanisms that fail to properly sanitize user-supplied data before rendering it in web pages. When victims browse to pages containing these compromised fields, their browsers execute the injected scripts, creating a persistent threat vector that can compromise user sessions and account integrity.
The technical implementation of this flaw typically occurs when the application stores user input without proper sanitization and subsequently reflects that input in HTML output without appropriate encoding measures. This allows attackers to craft malicious payloads that persist in the database or application storage, making the vulnerability particularly dangerous as it affects all users who encounter the compromised content. The stored nature of this XSS vulnerability means that once injected, the malicious script remains active until manually removed from the system, providing attackers with extended opportunities for exploitation.
From an operational impact perspective, this vulnerability creates significant risk for both end-users and system administrators within Adobe Commerce environments. Attackers can leverage this flaw to steal session cookies, perform unauthorized actions on behalf of users, redirect victims to malicious sites, or even escalate privileges within the application's access control model. The low privilege requirement for exploitation makes this vulnerability particularly concerning as it can be leveraged by attackers with minimal initial access rights, potentially leading to broader system compromise and data breaches.
Security professionals should implement comprehensive mitigation strategies that include input validation at multiple layers, output encoding of all user-supplied content, regular security scanning of application components, and strict access controls for form field modifications. The vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws in web applications, and maps to ATT&CK technique T1531 which covers 'Modify System Image' through the manipulation of web application interfaces. Organizations must also consider implementing content security policies, regular security training for developers, and automated testing procedures to detect similar vulnerabilities in other application components. The scope limitation mentioned in the description suggests that while the vulnerability is present, its impact may be constrained by specific application configurations or user access controls, but this does not diminish the fundamental security risk it presents to the overall system integrity.
