CVE-2025-46960 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 within the AEM platform, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim user accesses the affected page containing the maliciously crafted input, the injected script executes in their browser context. This stored XSS can lead to a range of attacks including session hijacking, credential theft, unauthorized actions performed on behalf of the user, and distribution of malware. The vulnerability requires low privileges to exploit but does require user interaction, as the victim must browse to the compromised page. The CVSS 3.1 base score is 5.4 (medium severity), reflecting network attack vector, low attack complexity, low privileges required, and user interaction needed. The scope is changed (S:C), indicating that the vulnerability affects components beyond the initially vulnerable component, potentially impacting confidentiality and integrity but not availability. No known exploits are currently reported in the wild, and no official patches have been linked yet. However, given the widespread use of Adobe Experience Manager in enterprise content management and web experience delivery, this vulnerability poses a significant risk if left unmitigated.

For European organizations, the impact of this vulnerability can be substantial due to the prevalent use of Adobe Experience Manager in government portals, financial institutions, healthcare providers, and large enterprises across Europe. Exploitation could lead to unauthorized access to sensitive user data, defacement of public-facing websites, and erosion of user trust. Confidentiality breaches could expose personal data protected under GDPR, leading to regulatory penalties and reputational damage. Integrity impacts could allow attackers to manipulate content or inject malicious scripts that propagate further attacks such as phishing or malware distribution. Although availability is not directly affected, the indirect consequences of compromised integrity and confidentiality can disrupt business operations and customer interactions. Organizations relying on AEM for critical web services should consider this vulnerability a priority for remediation to maintain compliance and security posture.

1. Immediate mitigation should include implementing strict input validation and output encoding on all user-supplied data fields within Adobe Experience Manager forms to prevent script injection. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers, limiting the impact of any injected malicious code. 3. Monitor and audit web application logs for unusual input patterns or repeated attempts to inject scripts. 4. Restrict privileges of users who can submit data to vulnerable forms to minimize the risk of malicious input. 5. Segregate and harden administrative interfaces to reduce exposure. 6. Stay alert for official Adobe patches or updates addressing CVE-2025-46960 and apply them promptly once available. 7. Conduct regular security assessments and penetration tests focusing on XSS vulnerabilities in web applications. 8. Educate users and administrators about the risks of XSS and safe browsing practices to reduce the likelihood of successful exploitation.
