CVE-2025-46876 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 systems running versions 6.5.22 and earlier contain a critical stored cross-site scripting vulnerability that allows low privilege attackers to inject malicious javascript code into form fields. This vulnerability exists due to insufficient input validation and output sanitization mechanisms within the content management system's form processing components. The flaw specifically affects the way the platform handles user input submitted through web forms, failing to properly escape or filter special characters that could be interpreted as executable code by web browsers. Attackers can exploit this weakness by submitting malicious payloads through accessible form fields, which are then stored within the application's database or content repository. When other users navigate to pages containing these compromised form fields, their browsers execute the injected javascript code in the context of their authenticated sessions, potentially leading to unauthorized actions or data exfiltration.
The technical exploitation of this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications. This weakness enables attackers to bypass normal access controls and execute arbitrary code within victim browsers, potentially compromising user sessions and accessing sensitive information. The vulnerability's impact is amplified by the fact that it operates as a stored XSS variant, meaning the malicious payload persists in the application's data stores rather than requiring immediate user interaction to be triggered. This characteristic makes the attack more persistent and harder to detect compared to reflected XSS attacks where the malicious code must be injected through a direct link or request. The low privilege requirement for exploitation indicates that even users with minimal access rights can potentially compromise the system's security posture.
Operational consequences of this vulnerability extend beyond simple script execution, as it can enable attackers to perform session hijacking, steal user credentials, modify content, or redirect users to malicious websites. The compromised Adobe Experience Manager environment could serve as a launching point for broader attacks within the organization's network infrastructure, especially if the platform hosts sensitive corporate data or serves as a gateway to other systems. The vulnerability's presence in the content management system also raises concerns about the integrity of published content, as attackers could inject malicious scripts into web pages that are distributed to end users. Organizations relying on Adobe Experience Manager for digital publishing and web content management face significant risk exposure, particularly in environments where the platform handles user-generated content or serves as a public-facing website platform.
Security mitigations for this vulnerability should prioritize immediate patching of Adobe Experience Manager installations to versions that address the stored XSS flaw. Organizations must implement comprehensive input validation and output encoding mechanisms across all form processing components to prevent malicious payloads from being stored or executed. Web application firewalls should be configured to detect and block common XSS attack patterns, while security monitoring systems should be enhanced to identify anomalous form submission patterns that could indicate exploitation attempts. Regular security assessments of the content management platform should include thorough testing of input handling mechanisms and validation of output encoding practices. Additionally, privileged access controls should be enforced to limit who can submit content through forms, and security awareness training should be provided to content creators to help them understand the risks of including untrusted input in web forms. The remediation process should also involve reviewing and updating the application's security configuration to ensure that all input validation rules are properly implemented and that output sanitization occurs at multiple layers of the application stack.
