CVE-2025-46950 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. Stored XSS vulnerabilities are particularly dangerous because the malicious payload is saved on the server and served to multiple users, increasing the attack surface and potential impact. The vulnerability requires low privileges to exploit but does require user interaction, as the victim must visit the compromised page. The CVSS 3.1 base score is 5.4 (medium severity), reflecting that the attack vector is network-based, with low attack complexity, requiring privileges and user interaction. The impact affects confidentiality and integrity, as the attacker can steal session tokens, perform actions on behalf of the user, or manipulate displayed content. Availability is not impacted. The vulnerability scope is changed (S:C), meaning the attack can affect components beyond the initially vulnerable component, potentially impacting the broader application environment. No known exploits are currently reported in the wild, and no official patches are linked yet, indicating that organizations should prioritize monitoring and mitigation efforts. Adobe Experience Manager is a widely used enterprise content management system, often deployed in large organizations for managing web content, digital assets, and customer experiences, making this vulnerability relevant for organizations relying on AEM for critical web infrastructure.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to the confidentiality and integrity of their web applications and user data. Attackers exploiting this flaw could hijack user sessions, steal sensitive information, or manipulate web content, potentially leading to reputational damage, regulatory non-compliance (e.g., GDPR violations due to data leakage), and operational disruptions. Since AEM is often used by government agencies, financial institutions, and large enterprises in Europe, the impact could extend to critical public-facing services and internal portals. The stored nature of the XSS means that multiple users can be affected once the malicious script is injected, increasing the risk of widespread compromise. Additionally, the changed scope of the vulnerability suggests that the attacker might leverage this flaw to affect other components or services integrated with AEM, amplifying the potential damage. Although no active exploits are reported, the medium severity score and ease of exploitation by low-privileged users necessitate proactive defense measures to prevent exploitation and protect sensitive European user data and services.

1. Immediate mitigation should include implementing strict input validation and output encoding on all form fields within Adobe Experience Manager to prevent injection of malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing AEM-managed sites. 3. Restrict privileges of users who can submit content to the vulnerable forms, minimizing the risk of malicious input from low-privileged accounts. 4. Monitor web application logs and user activity for unusual behavior indicative of XSS exploitation attempts. 5. Apply web application firewalls (WAFs) with rules specifically designed to detect and block XSS payloads targeting AEM. 6. Stay updated with Adobe’s security advisories and apply official patches or updates as soon as they become available. 7. Conduct regular security assessments and penetration testing focused on AEM deployments to identify and remediate similar vulnerabilities proactively. 8. Educate users and administrators about the risks of XSS and safe content management practices within AEM environments.
