CVE-2025-46895 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises from insufficient input sanitization in certain form fields, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim user accesses the affected page containing the injected script, the malicious code executes in their browser context. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS v3.1 base score is 5.4 (medium severity), with the vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, meaning the attack can be performed remotely over the network with low complexity, requires low privileges, and user interaction is necessary. The vulnerability impacts confidentiality and integrity by potentially allowing session hijacking, credential theft, or unauthorized actions performed in the context of the victim's session. Availability is not impacted. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component, such as other users' sessions. Stored XSS in AEM is particularly concerning because AEM is widely used for enterprise content management and web content delivery, often hosting public-facing websites and intranet portals, making it a valuable target for attackers aiming to compromise users or steal sensitive information.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to web application security and user trust. Exploitation could lead to unauthorized access to user sessions, theft of credentials, or injection of malicious content that damages brand reputation. Given AEM's role in managing critical digital assets and customer-facing portals, successful attacks could disrupt business operations, lead to data breaches involving personal data protected under GDPR, and cause regulatory compliance issues. The medium severity score reflects that while exploitation requires some user interaction and low privileges, the potential for cross-user impact and data leakage is non-trivial. Organizations in sectors such as finance, government, healthcare, and e-commerce that rely on AEM for digital engagement are particularly vulnerable. Additionally, the stored nature of the XSS means that malicious scripts can persist and affect multiple users over time, increasing the attack surface and potential damage.

European organizations should prioritize the following mitigations: 1) Apply security patches from Adobe as soon as they become available; monitor Adobe security advisories closely. 2) Implement strict input validation and output encoding on all user-supplied data in AEM forms to prevent injection of malicious scripts. 3) Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts and reduce XSS impact. 4) Conduct thorough security testing, including automated and manual penetration testing focused on XSS vulnerabilities in AEM deployments. 5) Educate users and administrators about the risks of clicking untrusted links or submitting untrusted content. 6) Use web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting AEM. 7) Review and minimize privileges of users who can submit content to reduce the risk from low-privileged attackers. 8) Monitor logs for suspicious activity indicative of XSS exploitation attempts. These measures, combined with timely patching, will significantly reduce the risk posed by this vulnerability.
