CVE-2025-47022 is a stored DOM-based 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 the affected page containing the maliciously crafted input, the injected script executes in their browser context. This type of XSS attack can lead to session hijacking, unauthorized actions on behalf of the user, defacement, or redirection to malicious sites. 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), reflecting that the attack vector is network-based, requires low privileges, and user interaction is necessary to trigger the payload. The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component, potentially impacting confidentiality and integrity but not availability. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that organizations should prioritize monitoring and mitigation efforts proactively. Given AEM's role as a content management system widely used for enterprise web content delivery, exploitation could compromise the integrity of web content and user trust.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Adobe Experience Manager to manage public-facing websites or intranet portals. Successful exploitation could lead to theft of user credentials, session tokens, or other sensitive information, enabling further attacks such as privilege escalation or data exfiltration. The integrity of web content could be compromised, damaging brand reputation and customer trust. Additionally, regulatory compliance risks arise, particularly under GDPR, if personal data is exposed or manipulated. The requirement for user interaction means phishing or social engineering could be used to lure victims to vulnerable pages, increasing the attack surface. Since AEM is often used by government, financial, and large enterprise sectors in Europe, the potential for targeted attacks to disrupt services or conduct espionage is notable. The medium severity score suggests that while the vulnerability is not critical, it still poses a meaningful risk that should be addressed promptly to prevent exploitation.

Organizations should implement the following specific mitigations: 1) Immediately review and sanitize all user inputs in AEM form fields to ensure proper encoding and validation, preventing script injection. 2) Apply any available Adobe security updates or patches as soon as they are released; if patches are not yet available, consider temporary workarounds such as disabling or restricting vulnerable form functionalities. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing AEM content. 4) Conduct thorough security testing, including automated and manual penetration tests focusing on XSS vectors within AEM deployments. 5) Educate users and administrators about the risks of clicking untrusted links or submitting unverified content. 6) Monitor web server and application logs for unusual activity indicative of attempted XSS exploitation. 7) Segment and harden the network environment hosting AEM to limit lateral movement if an attack occurs. These targeted actions go beyond generic advice by focusing on both immediate containment and long-term prevention tailored to the AEM environment.
