CVE-2025-46943 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 platform. When a victim subsequently visits a page containing the compromised form field, the injected script executes in their browser context. Stored XSS vulnerabilities are particularly dangerous because the malicious payload is persistently stored on the server and served to multiple users, increasing the attack surface. The vulnerability is classified under CWE-79, indicating improper neutralization of input leading to script injection. 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 with low attack complexity, requires low privileges, and user interaction (visiting the page) is needed. The vulnerability impacts confidentiality and integrity by potentially allowing attackers to steal session tokens, perform actions on behalf of users, or manipulate displayed content. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. Given AEM's role as a content management system widely used by enterprises for web content delivery, exploitation could lead to significant reputational damage and data exposure.

For European organizations, the impact of this vulnerability can be significant due to the widespread use of Adobe Experience Manager in government, financial, healthcare, and large enterprise sectors across Europe. Exploitation could lead to unauthorized access to sensitive information, session hijacking, and manipulation of web content, undermining user trust and potentially violating GDPR requirements related to data protection and breach notification. Since the vulnerability requires low privileges but user interaction, targeted phishing or social engineering campaigns could amplify the risk. Additionally, the cross-site scripting flaw could be leveraged as a foothold for further attacks within an organization's network, especially if combined with other vulnerabilities or misconfigurations. The medium severity score suggests a moderate but non-negligible risk, warranting prompt attention to prevent exploitation that could disrupt business operations or compromise customer data.

European organizations should immediately audit their Adobe Experience Manager deployments to identify affected versions (6.5.22 and earlier). Until an official patch is released, organizations should implement strict input validation and output encoding on all form fields to neutralize potentially malicious scripts. Employing Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting AEM can provide a temporary defense layer. Additionally, organizations should review user privilege assignments to minimize the number of users with permissions to submit or modify content in vulnerable fields. Security teams should monitor web traffic and logs for unusual activity indicative of attempted XSS exploitation. Educating users about the risks of clicking suspicious links and encouraging the use of modern browsers with built-in XSS protections can reduce the likelihood of successful attacks. Once Adobe releases a patch, organizations must prioritize timely deployment and validate the fix in their environments. Finally, adopting Content Security Policy (CSP) headers can help mitigate the impact of injected scripts by restricting script execution sources.
