CVE-2025-46983 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises from insufficient sanitization of user input in certain form fields, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim subsequently accesses the affected page containing the malicious payload, the injected script executes in their browser context. This can lead to unauthorized actions such as session hijacking, credential theft, or the execution of arbitrary actions on behalf of the victim within the scope of the vulnerable application. The vulnerability has a CVSS v3.1 base score of 5.4, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) shows that the attack can be performed remotely over the network with low attack complexity, requires low privileges, and user interaction is needed (the victim must visit the malicious page). The vulnerability impacts confidentiality and integrity but does not affect availability. The scope is changed, meaning the vulnerability can affect resources beyond the initially vulnerable component. No known exploits are currently reported in the wild, and no official patches or mitigation links have been published yet. Given Adobe Experience Manager's role as a content management system widely used for building and managing websites, this vulnerability can be leveraged to compromise user trust, steal sensitive information, or facilitate further attacks such as phishing or malware distribution.

For European organizations, the impact of CVE-2025-46983 can be significant, especially for those relying on Adobe Experience Manager to manage public-facing websites or intranet portals. Exploitation could lead to the compromise of user sessions, leakage of sensitive data, and defacement or manipulation of web content. This undermines the confidentiality and integrity of organizational data and can damage brand reputation and customer trust. Additionally, regulatory frameworks such as the GDPR impose strict requirements on data protection and breach notification, so exploitation could result in legal and financial consequences. Organizations in sectors like finance, healthcare, government, and e-commerce, which often use AEM for digital services, may face increased risk. The vulnerability’s requirement for user interaction means social engineering or phishing campaigns could be used to lure victims to malicious pages, amplifying the threat. The lack of available patches increases the urgency for organizations to implement interim mitigations to reduce exposure.

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 accessing affected web pages. 3. Use web application firewalls (WAFs) with custom rules to detect and block malicious payloads targeting known vulnerable form fields. 4. Conduct thorough code reviews and security testing on custom AEM components and templates to identify and remediate injection points. 5. Educate users and administrators about the risks of clicking untrusted links and encourage vigilance against phishing attempts. 6. Monitor web server and application logs for unusual activities indicative of exploitation attempts. 7. Plan and prioritize upgrading Adobe Experience Manager to a version where this vulnerability is patched once Adobe releases an official fix. 8. Isolate critical AEM instances behind additional security layers and limit access to trusted users to reduce the attack surface.
