CVE-2025-46898 is a stored DOM-based 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 compromised form field, the injected script executes in their browser context. The vulnerability arises due to insufficient input validation and sanitization of user-supplied data in form fields, which is then stored and rendered in the DOM without proper encoding. The CVSS 3.1 base score is 5.4 (medium severity), reflecting that the attack vector is network-based, requires low privileges, and user interaction is necessary (the victim must visit the affected page). 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. Exploitation could lead to theft of session tokens, user impersonation, or execution of arbitrary actions within the victim’s browser session, compromising confidentiality and integrity of user data and interactions within AEM. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is categorized under CWE-79, which is a common and well-understood class of XSS vulnerabilities.

For European organizations using Adobe Experience Manager, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive content managed via AEM portals. A successful exploit could allow attackers to hijack user sessions, steal credentials, or perform unauthorized actions on behalf of legitimate users, potentially leading to data breaches or defacement of web content. Given AEM’s widespread use in enterprise content management, marketing websites, and intranet portals across Europe, exploitation could disrupt business operations and damage organizational reputation. The medium severity score suggests that while the vulnerability is not critical, it still requires prompt attention to prevent exploitation. Organizations handling personal data under GDPR must consider the regulatory implications of any data compromise resulting from this vulnerability. The requirement for user interaction (visiting a maliciously crafted page) means social engineering or phishing could be used to trigger attacks, increasing the risk to end users and administrators alike.

European organizations should immediately audit their AEM deployments to identify affected versions (6.5.22 and earlier). Until an official patch is released, implement strict input validation and output encoding on all form fields to prevent injection of malicious scripts. Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts and reduce XSS impact. Limit user privileges to the minimum necessary to reduce the attack surface, especially for users who can submit data to vulnerable forms. Monitor web traffic and logs for unusual activity indicative of XSS exploitation attempts. Educate users and administrators about the risks of clicking untrusted links or submitting data to unknown sources within AEM portals. Once Adobe releases a patch, prioritize timely deployment. Additionally, consider deploying web application firewalls (WAFs) with rules targeting known XSS patterns to provide an additional layer of defense.
