CVE-2025-46962 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, allowing a low-privileged attacker to inject malicious JavaScript code that is stored on the server. When a victim user accesses a page containing the vulnerable form field, the malicious script executes in their browser context. This type of stored XSS can lead to session hijacking, credential theft, unauthorized actions on behalf of the user, or distribution of malware. The vulnerability requires the attacker to have some level of access to submit data (low privilege), and user interaction is necessary for exploitation, as the victim must visit the compromised page. The CVSS 3.1 base score is 5.4 (medium severity), reflecting network attack vector, low attack complexity, low privileges required, and user interaction needed. The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable module, potentially impacting confidentiality and integrity but not availability. No known exploits are currently reported in the wild, and no patches have been linked yet. 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. Exploitation could lead to unauthorized script execution in users' browsers, resulting in data theft, session hijacking, or defacement of web content. This undermines user trust and can lead to reputational damage, regulatory scrutiny under GDPR due to potential personal data exposure, and operational disruptions. Organizations in sectors such as finance, government, healthcare, and e-commerce, which often use AEM for digital experience management, are particularly at risk. The vulnerability's ability to affect confidentiality and integrity without impacting availability means attackers could stealthily compromise data or user sessions without immediate detection. The requirement for user interaction means phishing or social engineering could be used to lure victims to vulnerable pages, increasing the attack surface. The absence of known exploits currently provides a window for mitigation before widespread attacks occur.

Organizations should prioritize upgrading Adobe Experience Manager to a version beyond 6.5.22 once Adobe releases an official patch addressing CVE-2025-46962. Until a patch is available, implement strict input validation and sanitization on all user-submitted data fields within AEM, employing web application firewalls (WAFs) with custom rules to detect and block malicious script payloads. Conduct thorough code reviews and penetration testing focusing on XSS vectors in AEM deployments. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Educate users and administrators about the risks of clicking on untrusted links and encourage vigilance against phishing attempts that could lead to exposure to malicious pages. Monitor web logs for unusual input patterns or repeated attempts to inject scripts. Additionally, segment and restrict access to AEM administrative interfaces to minimize the risk of low-privileged attackers submitting malicious content. Regularly back up website content to enable quick restoration if defacement occurs.
