CVE-2025-46893 in Experience Manager
Summary
by MITRE • 06/11/2025
Adobe Experience Manager versions 6.5.22 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by a low privileged attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field.

Adobe Experience Manager represents a comprehensive digital experience platform that serves as a cornerstone for enterprise web content management and digital marketing operations. The platform's widespread adoption across organizations makes it an attractive target for cyber adversaries seeking to exploit vulnerabilities that could compromise large-scale digital ecosystems. This particular vulnerability resides within the form handling mechanisms of the software, specifically affecting versions 6.5.22 and earlier, which indicates a significant attack surface considering the platform's enterprise deployment scope. The vulnerability's classification as a stored XSS flaw means that malicious payloads persist within the application's database or storage mechanisms, creating a persistent threat vector that can affect multiple users over time.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding within the form field processing components of Adobe Experience Manager. When users submit data through forms, the application fails to properly sanitize or encode the input before storing it in the system. This allows an attacker with low privilege access to inject malicious JavaScript code directly into form fields that are subsequently rendered to other users. The vulnerability's persistence is particularly concerning as the malicious code becomes part of the application's legitimate data store, meaning that even after the initial injection, the payload continues to execute whenever the affected content is accessed. The attack requires minimal privileges, making it accessible to users who may not have administrative access but still possess the ability to submit form data, which is common in many enterprise environments where content authors or contributors have form submission capabilities.
The operational impact of this vulnerability extends beyond simple script execution, creating potential pathways for more sophisticated attacks within the enterprise environment. When a victim's browser executes the injected JavaScript, it can perform actions such as stealing session cookies, redirecting users to malicious sites, or even executing additional payloads that could lead to full system compromise. The stored nature of the vulnerability means that the attack can be executed repeatedly against multiple users without requiring the attacker to re-inject the malicious code each time. This characteristic significantly amplifies the potential damage and makes the vulnerability particularly dangerous in environments where multiple users regularly access the same content or forms. The attack vector is also stealthy, as the malicious code operates within the legitimate application context, making detection more challenging for security monitoring systems.
Organizations utilizing affected versions of Adobe Experience Manager should prioritize immediate remediation through official patches provided by Adobe, as this vulnerability represents a critical security risk. The implementation of additional defensive measures including web application firewalls, content security policies, and enhanced input validation should be considered as temporary mitigations while permanent fixes are deployed. Security teams should also conduct comprehensive assessments of their form-based applications to identify any other potential injection points that may exhibit similar vulnerabilities. The vulnerability aligns with CWE-79 which specifically addresses cross-site scripting flaws in web applications, and it maps to ATT&CK technique T1566.001 which covers spearphishing through social media and email campaigns that could leverage such vulnerabilities to establish initial access. Regular security testing and penetration testing of web applications should include comprehensive XSS vulnerability assessments to identify and remediate similar issues before they can be exploited by adversaries.
