CVE-2025-46968 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 persistently stored on the server. When a victim user accesses a page containing the compromised form field, the malicious 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 launched remotely over the network, requires low privileges, and user interaction is needed (victim must visit the affected page). The vulnerability impacts confidentiality and integrity by allowing script execution that could steal session tokens, perform actions on behalf of the user, or manipulate displayed content. Availability is not affected. No known exploits in the wild have been reported yet, and no official patches or mitigation links are provided at this time. The vulnerability’s scope is changed (S:C), indicating that the attack could affect resources beyond the vulnerable component, potentially impacting other users or systems within the same domain. Stored XSS in a widely used enterprise content management system like AEM poses a significant risk, especially in environments where multiple users access shared content and sensitive information is handled.

For European organizations, the impact of this vulnerability can be substantial. Adobe Experience Manager is widely used by enterprises, government agencies, and large organizations across Europe to manage digital content and customer experiences. Exploitation could lead to session hijacking, unauthorized actions performed under the victim’s credentials, and theft of sensitive information such as personal data or corporate secrets. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and financial losses. Since the vulnerability requires user interaction, phishing or social engineering campaigns could be used to lure users to vulnerable pages. The scope change means that attackers might leverage this flaw to compromise multiple users or systems within an organization’s web environment, amplifying the impact. European organizations with public-facing AEM portals or intranets are particularly at risk, especially those in regulated sectors like finance, healthcare, and government where data confidentiality and integrity are paramount.

Beyond generic advice, European organizations should implement the following specific mitigations: 1) Immediately audit all AEM instances to identify versions 6.5.22 or earlier and prioritize their upgrade to the latest patched version once available. 2) Apply strict Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 3) Conduct thorough input validation and output encoding on all user-supplied data in custom AEM components or templates to prevent injection of malicious scripts. 4) Use web application firewalls (WAFs) with rules tuned to detect and block common XSS payloads targeting AEM. 5) Educate users and administrators about the risks of clicking untrusted links and the importance of reporting suspicious activity. 6) Monitor logs and user behavior for anomalies that could indicate exploitation attempts. 7) Segment AEM environments and restrict administrative access to minimize the potential damage from compromised accounts. 8) Engage in regular security testing, including automated scanning and manual penetration testing focused on XSS vulnerabilities in AEM deployments.
