CVE-2025-46975 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises from insufficient sanitization of user input in certain form fields, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim subsequently accesses a page containing the compromised form field, the malicious script executes within their browser context. This DOM-based XSS attack can lead to unauthorized actions such as session hijacking, credential theft, or unauthorized manipulation of web content. The vulnerability has a CVSS v3.1 score of 5.4 (medium severity), reflecting that it requires network access, low attack complexity, low privileges, and user interaction, but impacts confidentiality and integrity with no direct availability impact. The scope is changed (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. No known exploits are currently reported in the wild, and no patches have been linked yet. Given Adobe Experience Manager's role as a content management system widely used by enterprises for web content delivery, exploitation of this vulnerability could facilitate targeted attacks against users interacting with affected web portals.

For European organizations, the impact of this vulnerability can be significant, especially for entities relying on Adobe Experience Manager for public-facing websites or internal portals. Successful exploitation could lead to theft of sensitive user data, including authentication tokens or personal information, undermining user trust and potentially violating GDPR requirements on data protection. The integrity of displayed content could be compromised, enabling phishing or misinformation campaigns. Although the vulnerability does not directly affect availability, the reputational damage and potential regulatory penalties could be substantial. Organizations in sectors such as finance, government, healthcare, and e-commerce, which often use AEM for digital engagement, may face increased risk. Additionally, the requirement for user interaction means that social engineering or phishing could be leveraged to increase exploitation success rates.

Organizations should prioritize upgrading Adobe Experience Manager to the latest version once Adobe releases a security patch addressing CVE-2025-46975. In the interim, administrators should implement strict input validation and output encoding on all user-supplied data fields within AEM to prevent script injection. Employing Content Security Policy (CSP) headers can help mitigate the impact by restricting the execution of unauthorized scripts. Web Application Firewalls (WAFs) should be configured to detect and block typical XSS payloads targeting AEM endpoints. Regular security audits and penetration testing focused on web application inputs can help identify residual injection points. User awareness training to recognize suspicious links or content can reduce the likelihood of successful exploitation. Monitoring logs for unusual activity related to form submissions or script execution is also recommended to detect potential exploitation attempts early.
