CVE-2025-64610 in Experience Manager
Summary
by MITRE • 09/08/2026
Adobe Experience Manager 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. Scope is changed.

Adobe Experience Manager contains a stored Cross-Site Scripting vulnerability within its content management and form processing subsystems, specifically affecting how user-supplied data is rendered back into web pages without adequate sanitization or encoding. This flaw allows an attacker with low-privileged access to inject malicious JavaScript code directly into vulnerable form fields during the initial submission phase. Unlike reflected XSS where the payload is delivered via a crafted link, stored XSS persists on the target server because the injected script becomes part of the page content itself. Consequently, every user who subsequently views or interacts with the affected page will have their browser execute the malicious script in the context of the vulnerable application domain.
The technical mechanism behind this vulnerability involves insufficient input validation and output encoding within the Adobe Experience Manager interface components that handle dynamic form data. When a low-privileged attacker submits a payload containing executable JavaScript, the system fails to properly escape special characters such as angle brackets or quotes before storing the content in its backend database or rendering it for display. This lack of proper sanitization enables the browser's parser to interpret the injected code as active script rather than static text data. The scope change noted indicates that previously restricted attack vectors may now be accessible, potentially expanding the range of actions an attacker can perform through this single entry point by leveraging the trust relationship between the victim’s browser and the Adobe Experience Manager server.
The operational impact of exploiting this vulnerability is significant as it facilitates session hijacking, credential theft, defacement, or redirection to malicious sites without requiring user interaction beyond visiting a compromised page. Attackers can steal sensitive cookies containing authentication tokens, allowing them to impersonate legitimate users including administrators if they gain access to privileged pages. Furthermore, the ability to execute arbitrary JavaScript enables phishing attacks where fake login forms are injected into existing interfaces to harvest credentials from unsuspecting visitors. In enterprise environments running Adobe Experience Manager, this could lead to unauthorized modification of digital assets, disruption of content delivery services, and compromise of downstream systems if the attacker leverages browser-side capabilities like keylogging or DOM manipulation to escalate privileges further within the application logic.
Mitigation strategies should focus on implementing robust input validation and output encoding practices consistent with industry standards such as CWE-79 for Cross-Site Scripting. Developers must ensure that all user-supplied data is strictly validated against expected formats before storage and encoded appropriately using context-aware escaping techniques when rendered in HTML, JavaScript, or URL contexts to prevent interpretation as executable code. Additionally, deploying Content Security Policy headers can help mitigate the impact by restricting script sources and preventing inline execution of untrusted scripts even if injection occurs. Regular security audits and penetration testing should be conducted to identify similar vulnerabilities across other modules within Adobe Experience Manager while keeping software updated with vendor-provided patches that address these specific encoding flaws in form handling components.
