CVE-2025-46932 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 platform. When a victim subsequently 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 side, increasing the likelihood of multiple victims being affected. The vulnerability arises due to insufficient input validation or output encoding of user-supplied data in form fields, enabling script injection. The CVSS v3.1 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 required (UI:R), scope changed (S:C), and impacts on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). The scope change indicates that the vulnerability affects components beyond the initially vulnerable component, potentially impacting other parts of the system or users. While no known exploits are currently reported in the wild, the vulnerability poses a risk especially in environments where multiple users access AEM-managed content. Attackers could leverage this to steal session tokens, perform actions on behalf of users, or deliver further malware payloads. Adobe has not yet published a patch or mitigation guidance at the time of this report.

For European organizations using Adobe Experience Manager, this vulnerability could lead to unauthorized disclosure of sensitive information, session hijacking, and potential compromise of user accounts or administrative functions. Given AEM's widespread use in enterprise content management, marketing websites, and intranet portals, exploitation could affect both internal users and external customers. The confidentiality and integrity of data processed or displayed via AEM could be compromised, leading to reputational damage, regulatory non-compliance (e.g., GDPR violations if personal data is exposed), and operational disruptions. Since the attack requires user interaction, phishing or social engineering could be used to lure victims to vulnerable pages. The medium severity score suggests moderate risk, but the potential for chained attacks or privilege escalation could increase impact. Organizations in sectors such as finance, healthcare, government, and media—where AEM is commonly deployed—may face higher risks due to the sensitivity of their data and regulatory scrutiny in Europe.

1. Immediate mitigation should include auditing all form fields in AEM for proper input validation and output encoding to prevent script injection. 2. Implement Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers. 3. Restrict user privileges to the minimum necessary, especially for users who can submit data to vulnerable forms. 4. Monitor web server and application logs for unusual input patterns or repeated attempts to inject scripts. 5. Educate users about the risks of clicking unknown links or interacting with suspicious content hosted on AEM sites. 6. Since no patch is currently available, consider temporary workarounds such as disabling vulnerable form features or isolating affected AEM instances from critical networks. 7. Plan for rapid deployment of official Adobe patches once released, including thorough testing in staging environments. 8. Employ web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting AEM. 9. Conduct regular security assessments and penetration testing focused on AEM deployments to identify and remediate similar vulnerabilities proactively.
