CVE-2025-46950 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 presents a critical stored cross-site scripting vulnerability in versions 6.5.22 and earlier, where malicious actors with low privilege access can inject persistent JavaScript payloads into form fields. This vulnerability operates through the improper sanitization of user input within the content management system's form handling mechanisms. The flaw allows attackers to store malicious scripts that execute whenever legitimate users view the affected pages containing the compromised form fields. The vulnerability specifically targets the application's handling of user-submitted data in web forms, where input validation and output encoding are insufficient to prevent script injection. This weakness enables attackers to bypass standard security controls and execute arbitrary code within the victim's browser context, potentially leading to session hijacking, credential theft, or further exploitation of the compromised environment.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding practices within Adobe Experience Manager's content rendering pipeline. When users submit data through web forms, the system fails to properly sanitize the input before storing it in the database or content repository. The stored data is then retrieved and rendered in subsequent page requests without appropriate context-aware encoding, creating an ideal environment for cross-site scripting attacks. This flaw aligns with CWE-79, which describes improper neutralization of input during web page generation, and represents a classic stored XSS scenario where malicious content persists server-side and executes in the victim's browser. The vulnerability's impact is amplified by the fact that it requires minimal privileges to exploit, making it particularly dangerous in environments where multiple users have access to form submission functionality.
The operational consequences of this vulnerability extend beyond simple script execution, as it provides attackers with a foothold for more sophisticated attacks within the Adobe Experience Manager environment. Once a malicious script executes in a victim's browser, attackers can potentially steal session cookies, redirect users to malicious sites, or harvest sensitive information from the application. The persistent nature of stored XSS means that the attack vector remains active until the vulnerable form field is properly sanitized or the malicious content is removed. This vulnerability also enables attackers to manipulate content displayed to users, potentially leading to defacement of web pages or the injection of additional malicious payloads. The attack surface is particularly concerning given that Adobe Experience Manager is commonly used for enterprise web applications where users may have elevated privileges or access to sensitive data.
Organizations utilizing Adobe Experience Manager versions 6.5.22 and earlier should immediately implement mitigations to address this vulnerability. The primary defense mechanism involves implementing comprehensive input validation and output encoding across all user-facing form fields and content submission points. Security patches from Adobe should be applied as soon as they become available to remediate the underlying code vulnerabilities. Additionally, organizations should consider implementing web application firewalls and content security policies to detect and prevent malicious script injection attempts. Regular security testing and code reviews should focus on input handling mechanisms and form validation logic to identify similar vulnerabilities. The mitigation strategy should align with ATT&CK technique T1566, which covers credential access through social engineering and malicious content delivery. Organizations should also establish monitoring procedures to detect unauthorized content modifications and implement proper access controls to limit the privilege levels of users who can submit content through vulnerable forms.
