CVE-2025-47089 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 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 launched remotely over the network, requires low privileges, and user interaction is needed (the victim must visit the malicious page). The impact affects confidentiality and integrity but not availability. The vulnerability scope is changed (S:C), indicating that the attack can affect resources beyond the vulnerable component. No known exploits are currently reported in the wild, and no official patches have been linked yet. Adobe Experience Manager is a widely used enterprise content management system, often deployed by large organizations for managing web content and digital assets. Stored XSS in such a platform can lead to session hijacking, credential theft, unauthorized actions on behalf of users, and potential pivoting within the affected environment.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to web application security and user trust. Exploitation could lead to theft of sensitive user credentials, session tokens, or other confidential information, potentially resulting in unauthorized access to internal systems or data breaches. Given AEM's role in managing corporate websites and intranet portals, attackers could manipulate content or perform actions with the privileges of authenticated users, including administrators. This could disrupt business operations, damage reputation, and lead to regulatory non-compliance under GDPR due to exposure of personal data. The medium severity score reflects that while exploitation requires some user interaction and low privileges, the potential for cross-site contamination and data leakage is notable. European organizations with public-facing AEM deployments or internal portals accessible by employees are particularly at risk, especially if they have not yet updated to patched versions or implemented compensating controls.

Organizations should prioritize the following mitigation steps: 1) Immediately review and apply any available security patches or updates from Adobe for AEM, specifically addressing CVE-2025-47089. 2) Implement strict input validation and output encoding on all form fields to prevent injection of malicious scripts. 3) Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers. 4) Conduct thorough security testing and code reviews on custom AEM components and templates to identify and remediate similar XSS risks. 5) Educate users and administrators about the risks of clicking untrusted links or interacting with suspicious content within AEM portals. 6) Monitor web server and application logs for unusual activity indicative of attempted XSS exploitation. 7) Consider deploying Web Application Firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting AEM. 8) Limit privileges of users who can submit content to the vulnerable forms to reduce attack surface. These targeted measures go beyond generic advice by focusing on AEM-specific controls and operational practices.
