CVE-2025-47086 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability allows a low-privileged attacker to inject malicious JavaScript code into vulnerable form fields within the AEM interface. When a victim user accesses a page containing the compromised form field, the injected script executes in their browser context. Stored XSS vulnerabilities are particularly dangerous because the malicious payload is persistently stored on the server and served to multiple users, increasing the attack surface and potential impact. The attack vector requires the attacker to have some level of access to submit data to the vulnerable form fields, but no elevated privileges beyond that. The CVSS v3.1 base score is 5.4, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) highlights that the attack can be launched remotely over the network with low attack complexity, requires low privileges, and user interaction is necessary (victim must visit the affected page). The vulnerability impacts confidentiality and integrity by allowing script execution that could steal session tokens, perform actions on behalf of the user, or manipulate displayed content. Availability is not impacted. No known exploits are currently reported in the wild, and no official patches or mitigation links are provided yet. Given the widespread use of Adobe Experience Manager in enterprise content management and digital experience platforms, this vulnerability poses a significant risk to organizations relying on AEM for web content delivery and internal portals.

For European organizations, the impact of this vulnerability can be substantial, especially for those using Adobe Experience Manager to manage customer-facing websites, intranets, or digital services. Exploitation could lead to theft of user credentials, session hijacking, defacement of websites, or unauthorized actions performed under the victim’s identity. This can result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data leakage), and potential financial losses. Since AEM is often integrated with other enterprise systems, a successful XSS attack could serve as a foothold for further lateral movement or data exfiltration. The requirement for user interaction means phishing or social engineering could be combined with this vulnerability to increase success rates. European organizations in sectors such as finance, government, healthcare, and retail, which heavily rely on secure web platforms, are particularly at risk. Additionally, the cross-site scripting vulnerability could undermine trust in digital services, which is critical in the European market where data privacy and security are highly regulated and scrutinized.

1. Immediate mitigation should include reviewing and restricting user input on all form fields in Adobe Experience Manager to ensure proper input validation and sanitization. 2. Implement Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 3. Apply strict output encoding on all user-supplied data rendered in web pages to prevent script injection. 4. Monitor and audit logs for unusual input patterns or repeated attempts to inject scripts. 5. Educate users to be cautious of unsolicited links or suspicious web content to reduce the risk of social engineering combined with this vulnerability. 6. Since no official patches are currently available, organizations should engage with Adobe support for any available workarounds or upcoming fixes. 7. Consider deploying Web Application Firewalls (WAFs) with rules to detect and block common XSS payloads targeting AEM. 8. Plan for rapid deployment of patches once Adobe releases them and test updates in staging environments to ensure compatibility. 9. Conduct regular security assessments and penetration testing focused on web application vulnerabilities including XSS to proactively identify and remediate similar issues.
