CVE-2025-46936 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Experience Manager (AEM) versions 6.5.22 and earlier. This vulnerability arises due to insufficient input sanitization in certain form fields within AEM, allowing a low-privileged attacker to inject malicious JavaScript code that is persistently stored on the affected system. When a victim user accesses a page containing the compromised form field, the malicious script executes in their browser context. The vulnerability is classified under CWE-79, indicating a classic XSS flaw. The CVSS v3.1 base score is 5.4 (medium severity), with the vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, meaning the attack can be launched remotely over the network with low attack complexity, requires low privileges, and user interaction (visiting the page) is necessary. The vulnerability impacts confidentiality and integrity by potentially allowing session hijacking, credential theft, or unauthorized actions performed in the victim's browser session. Availability is not affected. The scope is changed (S:C), indicating that the vulnerability could affect resources beyond the vulnerable component. No known exploits are currently reported in the wild, and no official patches or mitigation links are provided yet. Given AEM's widespread use in enterprise content management and web experience delivery, this vulnerability poses a risk to organizations relying on AEM for public-facing or internal web portals.

For European organizations, this vulnerability could lead to significant security risks, especially for those using Adobe Experience Manager to manage critical web content or customer-facing portals. Exploitation could enable attackers to steal session cookies, perform unauthorized actions on behalf of users, or deliver further malware payloads via injected scripts. This can result in data breaches, reputational damage, and regulatory non-compliance under GDPR if personal data is compromised. Since AEM is often used by large enterprises, government agencies, and service providers across Europe, the impact could extend to sensitive information exposure and disruption of trusted digital services. The requirement for low privileges to exploit increases the threat surface, as even less privileged insiders or external attackers with limited access could attempt exploitation. User interaction is needed, so phishing or social engineering could facilitate attacks. The medium severity score reflects a moderate but tangible risk that should be addressed promptly to avoid escalation or chaining with other vulnerabilities.

Organizations should immediately review their Adobe Experience Manager deployments and identify versions at or below 6.5.22. Until an official patch is released, implement strict input validation and output encoding on all form fields to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Monitor web application logs for suspicious input patterns indicative of XSS attempts. Educate users to recognize phishing attempts that may lead them to maliciously crafted pages. Restrict access to AEM administrative and content editing interfaces to trusted personnel only, minimizing the risk of low-privileged attackers injecting malicious content. Consider deploying Web Application Firewalls (WAFs) with rules targeting common XSS payloads as a temporary protective measure. Once Adobe releases a patch, prioritize its deployment in all affected environments. Additionally, conduct security testing and code reviews on custom AEM components to ensure no other injection points exist.
