CVE-2025-46935 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 within the AEM platform, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim user accesses a page containing the compromised form field, the malicious script executes in their browser context. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS 3.1 base score is 5.4 (medium severity), with vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, meaning the attack can be launched remotely over the network with low attack complexity, requires low privileges, and user interaction is needed to trigger the exploit. The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality and integrity to a limited extent but does not affect availability. No known exploits are currently reported in the wild, and no official patches have been linked yet. Stored XSS in a widely used enterprise content management system like AEM can facilitate session hijacking, credential theft, or unauthorized actions performed in the context of the victim's session, potentially leading to further compromise within the affected organization’s web environment.

For European organizations using Adobe Experience Manager, this vulnerability poses a moderate risk. AEM is commonly used by large enterprises, government agencies, and public sector organizations across Europe for managing digital content and websites. Exploitation could allow attackers to execute malicious scripts in the browsers of employees, partners, or customers, potentially leading to credential theft, session hijacking, or unauthorized actions on internal portals or public-facing sites. This can result in data leakage, reputational damage, and compliance issues, especially under GDPR regulations. Since the vulnerability requires low privileges but user interaction, phishing or social engineering may be leveraged to increase exploitation success. The scope change means that the attacker could affect resources beyond the initial vulnerable component, increasing the potential attack surface. Although no active exploits are reported, the medium severity and widespread use of AEM in Europe necessitate prompt attention to prevent targeted attacks, especially in sectors with sensitive data such as finance, healthcare, and government.

Organizations should immediately audit their Adobe Experience Manager installations to identify affected versions (6.5.22 and earlier). Until an official patch is released, implement the following mitigations: 1) Apply strict input validation and output encoding on all user-supplied data in form fields to neutralize malicious scripts. 2) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3) Limit user privileges to the minimum necessary to reduce the risk posed by low-privileged attackers. 4) Monitor web application logs for suspicious input patterns indicative of XSS attempts. 5) Educate users to recognize and avoid interacting with suspicious links or content that could trigger the vulnerability. 6) Consider deploying Web Application Firewalls (WAFs) with rules designed to detect and block XSS payloads targeting AEM. 7) Plan for rapid deployment of official Adobe patches once available. 8) Review and harden session management to mitigate session hijacking risks. These targeted steps go beyond generic advice by focusing on the specific context of AEM and stored XSS attack vectors.
