CVE-2025-46930 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability allows a low-privileged attacker to inject malicious JavaScript code into vulnerable form fields within the AEM interface. When a victim user accesses a page containing the injected malicious script, the script executes in their browser context. The vulnerability is classified as CWE-79, indicating improper neutralization of input during web page generation. The CVSS 3.1 score is 5.4 (medium severity), reflecting that the attack vector is network-based (AV:N), requires low privileges (PR:L), and user interaction (UI:R) is necessary for exploitation. The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component. The impact on confidentiality and integrity is low (C:L, I:L), with no impact on availability (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. Stored XSS vulnerabilities in AEM are particularly concerning because AEM is widely used by enterprises for content management and digital experience delivery, making it a valuable target for attackers seeking to compromise user sessions, steal credentials, or conduct phishing attacks within trusted environments.

For European organizations, the impact of this vulnerability can be significant due to the widespread adoption of Adobe Experience Manager in sectors such as government, finance, healthcare, and media. Exploitation could lead to session hijacking, unauthorized actions performed on behalf of users, and theft of sensitive data, undermining user trust and potentially violating GDPR requirements related to data protection and breach notification. The stored nature of the XSS means malicious scripts persist on the server and affect multiple users, increasing the attack surface. Additionally, the need for user interaction (visiting a maliciously crafted page) means social engineering could be leveraged to maximize impact. Compromise of AEM instances could also damage brand reputation and disrupt digital services critical to business operations.

European organizations should prioritize the following mitigation steps: 1) Immediately audit all AEM instances to identify vulnerable versions (6.5.22 and earlier) and plan for prompt upgrading to patched versions once available. 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 regular security testing, including automated scanning for XSS vulnerabilities and manual code reviews of custom AEM components. 5) Educate users and administrators about the risks of clicking untrusted links and the importance of reporting suspicious activity. 6) Monitor web server and application logs for unusual input patterns or error messages indicative of attempted exploitation. 7) Segment AEM infrastructure to limit lateral movement if compromise occurs. 8) Prepare incident response plans that include steps for containment and remediation of XSS attacks.
