CVE-2025-47000 is a stored Cross-Site Scripting (XSS) vulnerability identified in 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 malicious payload, the injected script executes in their browser context. This can lead to unauthorized actions such as session hijacking, credential theft, or unauthorized modification of content within the AEM environment. The vulnerability is classified under CWE-79, indicating a classic XSS flaw. 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 needed (UI:R), scope changed (S:C), and impacts on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's exploitation requires a user to interact with the maliciously crafted content, and the attacker must have some level of access to submit data to the vulnerable form fields, which somewhat limits the attack surface but still poses a significant risk in environments with multiple users or external contributors.

For European organizations using Adobe Experience Manager, this vulnerability can have serious consequences. AEM is widely used by enterprises, government agencies, and large institutions across Europe for managing web content and digital assets. Exploitation could lead to unauthorized disclosure of sensitive information, including user credentials and internal data, through session hijacking or theft of authentication tokens. Integrity of published content could be compromised, damaging organizational reputation and trust. Given the scope change indicated in the CVSS vector, the attack could affect users beyond the initially compromised component, potentially impacting multiple users or systems within the organization. This is particularly critical for sectors such as finance, healthcare, and public administration, where data confidentiality and integrity are paramount. Additionally, the requirement for user interaction means phishing or social engineering could be leveraged to increase the attack's effectiveness. The absence of known exploits currently provides a window for proactive mitigation, but the medium severity score suggests organizations should prioritize remediation to prevent potential future exploitation.

European organizations should implement the following specific mitigation steps: 1) Immediately audit all AEM instances to identify versions 6.5.22 and earlier and prioritize their upgrade to the latest patched version once available from Adobe. 2) Until patches are released, apply strict input validation and sanitization on all user-submitted data within AEM forms, potentially using web application firewalls (WAFs) with custom rules to detect and block suspicious script payloads. 3) Restrict form submission permissions to trusted users only, minimizing the risk of malicious input from low-privileged attackers. 4) Implement Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers accessing AEM content. 5) Conduct user awareness training focused on recognizing suspicious links or content that could trigger XSS attacks, reducing the risk from required user interaction. 6) Monitor AEM logs and network traffic for unusual activity indicative of attempted exploitation. 7) Coordinate with Adobe support channels to stay informed about patch releases and advisories. These measures, combined, will reduce the attack surface and mitigate the risk until official patches are deployed.
