CVE-2025-54252 is a stored Cross-Site Scripting (XSS) vulnerability identified in Adobe Experience Manager (AEM) versions 6.5.23.0 and earlier. This vulnerability arises from insufficient input sanitization in certain form fields, allowing an attacker with low privileges to inject malicious JavaScript code that is persistently stored on the server. When other users or administrators access the affected page containing the injected script, the malicious code executes in their browsers within the context of the vulnerable application. This can lead to bypassing security controls, such as same-origin policy protections, potentially enabling session hijacking, unauthorized actions, or data theft. The attack requires user interaction, meaning the victim must visit the compromised page for the exploit to succeed. The vulnerability has a CVSS 3.1 base score of 5.4, reflecting medium severity due to its network attack vector, low attack complexity, requirement for privileges, and user interaction. The scope is changed (S:C), indicating that the vulnerability affects components beyond the initially vulnerable component. No public exploits have been reported yet, but the risk remains significant given the widespread use of Adobe Experience Manager in enterprise content management and web applications. The vulnerability is tracked under CWE-79, a common and well-understood category of web application security flaws related to improper neutralization of input leading to script injection.

The primary impact of CVE-2025-54252 is on the confidentiality and integrity of data within affected Adobe Experience Manager deployments. Successful exploitation can allow attackers to execute arbitrary scripts in the context of users' browsers, potentially leading to session hijacking, theft of sensitive information such as authentication tokens or personal data, and unauthorized actions performed on behalf of users. While availability is not directly impacted, the compromise of user sessions or administrative accounts could lead to further attacks or data manipulation. Organizations relying on AEM for content management and customer-facing web portals are at risk of reputational damage, regulatory non-compliance, and operational disruption if attackers leverage this vulnerability. The requirement for user interaction limits the attack surface somewhat, but phishing or social engineering could be used to lure victims to vulnerable pages. Given Adobe Experience Manager's extensive deployment across industries including government, finance, healthcare, and retail, the potential impact is broad and significant.

To mitigate CVE-2025-54252, organizations should immediately upgrade Adobe Experience Manager to a version where this vulnerability is patched once available. In the absence of an official patch, implement strict input validation and output encoding on all form fields to prevent malicious script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Regularly audit and sanitize stored content to detect and remove injected scripts. Limit user privileges to the minimum necessary to reduce the risk of low-privileged attackers injecting malicious content. Educate users and administrators about the risks of clicking on untrusted links or visiting suspicious pages within the AEM environment. Monitor logs for unusual activity or script injection attempts. Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting AEM. Finally, maintain an incident response plan to quickly address any exploitation attempts.
