CVE-2025-47026 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 AEM, 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 injected script 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 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 attack complexity, requires low privileges, and user interaction is necessary to trigger the payload. The vulnerability impacts confidentiality and integrity by potentially allowing session hijacking, credential theft, or unauthorized actions performed in the context of the victim’s browser session. Availability is not impacted. The scope is changed (S:C), indicating that the vulnerability affects components beyond the vulnerable component itself. No known exploits are currently reported in the wild, and no patches are linked yet, suggesting that mitigation may rely on configuration or workaround until official fixes are released. Adobe Experience Manager is a widely used enterprise content management system, often deployed by large organizations for web content delivery and digital asset management, making this vulnerability relevant for entities relying on AEM for public-facing or internal portals.

For European organizations, the impact of this vulnerability can be significant due to the widespread use of Adobe Experience Manager in sectors such as government, finance, healthcare, and media. Exploitation could lead to unauthorized disclosure of sensitive information, session hijacking, or manipulation of web content, undermining user trust and potentially violating data protection regulations like GDPR. Since the vulnerability requires low privileges but user interaction, phishing or social engineering could be leveraged to increase attack success. The compromise of AEM portals could also facilitate further lateral movement or targeted attacks within an organization’s network. Additionally, reputational damage and regulatory penalties could arise from breaches caused by exploitation of this vulnerability. The medium severity score reflects a moderate risk, but the strategic importance of affected systems in Europe elevates the need for prompt attention.

1. Immediately review and restrict access permissions to AEM form fields and administrative interfaces to minimize the risk of low-privileged attackers injecting malicious scripts. 2. Implement strict input validation and output encoding on all user-supplied data in AEM forms to prevent script injection. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing AEM content. 4. Monitor web server and application logs for unusual input patterns or repeated form submissions that could indicate exploitation attempts. 5. Educate users about the risks of interacting with suspicious links or content hosted on AEM portals to reduce the likelihood of triggering the vulnerability. 6. Stay alert for official Adobe patches or security advisories addressing CVE-2025-47026 and apply updates promptly once available. 7. Consider deploying web application firewalls (WAF) with rules tailored to detect and block XSS payloads targeting AEM. 8. Conduct regular security assessments and penetration testing focused on web application vulnerabilities including stored XSS in AEM environments.
