CVE-2025-46907 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 visits a page containing the compromised form field, the injected script executes in their browser context. Stored XSS differs from reflected XSS in that the malicious payload is permanently stored on the server (e.g., in a database or content repository) and served to users, increasing the attack's persistence and reach. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS 3.1 base score is 5.4 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), user interaction (UI:R), scope changed (S:C), and impacts on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). The vulnerability's exploitation requires the attacker to have some level of authenticated access to inject the malicious script, and the victim must interact with the affected page to trigger the payload. No known exploits are reported in the wild yet, and no official patches or mitigation links are provided at this time. Given AEM's role as a content management system widely used by enterprises for managing web content and digital assets, this vulnerability could be leveraged to perform session hijacking, credential theft, or deliver further malware via the victim's browser, potentially compromising sensitive corporate data or user information.

For European organizations, the impact of this vulnerability can be significant due to the widespread use of Adobe Experience Manager in government, finance, healthcare, and large enterprises across Europe. Exploitation could lead to unauthorized access to sensitive information, defacement of public-facing websites, and erosion of user trust. Since the vulnerability allows script execution in the context of trusted domains, attackers could steal session cookies, perform actions on behalf of users, or redirect users to malicious sites. This is particularly concerning for organizations handling personal data protected under GDPR, as a breach could result in regulatory penalties and reputational damage. Additionally, the persistence of stored XSS means that once injected, the malicious script could affect multiple users over time, increasing the scope of impact. The requirement for low privileges to inject scripts means insider threats or compromised low-level accounts could be leveraged. The need for user interaction to trigger the payload somewhat limits automated mass exploitation but does not eliminate targeted attacks against high-value users or administrators.

Organizations should prioritize upgrading Adobe Experience Manager to the latest version once Adobe releases a patch addressing CVE-2025-46907. In the interim, administrators should review and harden input validation and output encoding on all form fields within AEM to prevent script injection. Employing Content Security Policy (CSP) headers can help mitigate the impact by restricting the execution of unauthorized scripts. Regularly auditing user permissions to ensure least privilege principles are enforced will reduce the risk of low-privileged attackers injecting malicious content. Monitoring web application logs for unusual input patterns or repeated form submissions can help detect attempted exploitation. Additionally, educating users about the risks of interacting with suspicious content and implementing multi-factor authentication can reduce the likelihood and impact of successful attacks. Web Application Firewalls (WAFs) configured to detect and block XSS payloads may provide temporary protection. Finally, organizations should prepare incident response plans specific to web application compromises involving XSS attacks.
