CVE-2025-46887 in Experience Manager
Summary
by MITRE • 06/11/2025
Adobe Experience Manager versions 6.5.22 and earlier are 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.

Adobe Experience Manager represents a comprehensive digital experience platform that enables organizations to create, manage, and deliver personalized web content across multiple channels. The platform serves as a critical component in enterprise digital strategies, handling sensitive user data through various form interactions and content management functionalities. This vulnerability resides within the core content management capabilities of the system, specifically targeting the form processing mechanisms that are fundamental to user engagement and data collection within the AEM environment.
The stored cross-site scripting vulnerability stems from inadequate input validation and output encoding within the form field processing pipeline. Attackers with low privileged access can exploit this weakness by submitting malicious JavaScript payloads through vulnerable form fields that are subsequently stored within the system's database. These payloads remain dormant until accessed by other users who view the affected pages containing the compromised form data. The vulnerability demonstrates a classic stored XSS flaw where the malicious script is permanently stored on the server and executed each time the compromised content is rendered to users. This represents a significant security gap in the platform's data sanitization processes, allowing attackers to bypass standard security controls through legitimate user interactions.
The operational impact of this vulnerability extends beyond simple script execution, as it provides attackers with the ability to hijack user sessions, steal sensitive cookies, and perform unauthorized actions on behalf of victims. When compromised users browse to pages containing the malicious form fields, their browsers execute the injected JavaScript code within the context of the legitimate AEM application, potentially leading to full account compromise and data exfiltration. The low privilege requirement for exploitation makes this vulnerability particularly dangerous as it can be leveraged by attackers with minimal access rights, potentially escalating to higher privileges through session hijacking or credential theft. This vulnerability directly impacts the integrity and confidentiality of user data, undermining the trust that organizations place in their digital experience platforms.
Organizations should immediately implement comprehensive input validation and output encoding mechanisms to sanitize all user-supplied data before storage and rendering. The mitigation strategy must include strict content security policy enforcement, regular security scanning of form fields, and implementation of web application firewalls to detect and block malicious payloads. Additionally, organizations should conduct thorough security assessments of their AEM installations to identify all potential form fields that may be vulnerable to similar attacks. This vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws in web applications, and maps to ATT&CK technique T1566 which covers social engineering through malicious content injection. Regular patch management and security updates should be prioritized, with organizations monitoring for official Adobe security advisories and implementing immediate remediation when available. The incident response plan should include procedures for identifying compromised form fields and notifying affected users of potential session hijacking or data compromise.
