CVE-2026-48253 in Experience Manager
Summary
by MITRE • 07/14/2026
Adobe Experience Manager is affected by a DOM-based Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this issue by manipulating the DOM environment to execute malicious JavaScript within the context of the victim's browser. Exploitation of this issue requires user interaction in that a victim must visit a crafted webpage. Scope is changed.

Adobe Experience Manager suffers from a dom-based cross-site scripting vulnerability that represents a critical security flaw in the application's handling of user input within the document object model environment. This vulnerability falls under CWE-79 which specifically addresses cross-site scripting flaws where malicious scripts are executed in the victim's browser context. The flaw occurs when the application fails to properly sanitize or validate user-supplied data that is subsequently processed within the DOM, creating an opening for attackers to inject malicious javascript code that executes in the victim's browser session.
The exploitation mechanism requires a sophisticated social engineering approach where attackers craft malicious web pages designed to manipulate the dom environment and execute unintended javascript code. This type of attack specifically leverages the browser's document object model to inject script payloads that can bypass traditional input validation mechanisms since they operate at the client-side level rather than server-side processing. The vulnerability is particularly concerning because it operates entirely within the browser context, making detection more challenging for network monitoring systems and traditional security controls.
The operational impact of this vulnerability extends beyond simple data theft or session hijacking to potentially enable complete browser compromise and unauthorized access to sensitive corporate data. Attackers can leverage this flaw to perform actions such as stealing user credentials, accessing confidential documents, modifying content within the AEM environment, and conducting further reconnaissance activities against the organization's digital infrastructure. The requirement for user interaction means that successful exploitation depends on convincing victims to visit malicious pages, making this a persistent threat vector that requires comprehensive user education and awareness programs alongside technical mitigations.
Organizations utilizing Adobe Experience Manager must implement comprehensive security measures including strict content security policy enforcement, proper input validation at multiple layers of the application architecture, and regular security testing of dom-based interactions. The vulnerability demonstrates the importance of addressing client-side security concerns as part of overall application security posture management. Mitigation strategies should include implementing strict sanitization of all user inputs, utilizing secure coding practices that prevent direct dom manipulation with untrusted data, and deploying web application firewalls that can detect and block suspicious javascript injection attempts. This vulnerability also highlights the need for continuous security monitoring and incident response procedures to identify potential exploitation attempts and respond rapidly to emerging threats in the digital ecosystem.
The attack vector aligns with ATT&CK technique T1059.007 which covers script-based execution through browser-based scripting languages, making this vulnerability particularly relevant to modern threat landscape assessment and defensive security architecture planning. Organizations should conduct regular penetration testing focused on dom-based vulnerabilities, implement proper security training for developers working with AEM platforms, and maintain up-to-date security patches to address known vulnerabilities in the Adobe Experience Manager ecosystem.
