Adobe Experience Manager versions 6.5.23 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability. This vulnerability allows low-privileged attackers to inject malicious scripts into vulnerable form fields. When a victim browses to a page containing the vulnerable field, the malicious JavaScript may be executed in their browser.
The CVSS score assigned to this vulnerability is 5.4, indicating a medium severity level. Organizations using affected versions should prioritize addressing this issue to mitigate potential exploit risks. The vulnerability was published on March 11, 2026, and has been classified as CWE-79, which pertains to improper neutralization of input during web page generation.
Currently, there is no public exploit confirmed for this vulnerability, but the potential for exploitation exists due to the nature of XSS vulnerabilities. Organizations should evaluate their exposure and implement necessary mitigations. Organizations should prioritize patching immediately.
As of now, Adobe has not included this vulnerability in their Known Exploited Vulnerabilities (KEV) catalog. However, with the increasing prevalence of web-based attacks, security teams must remain vigilant and proactive in their defense strategies.
Vulnerability Details
The vulnerability allows low-privileged attackers to inject malicious scripts into vulnerable form fields in Adobe Experience Manager. The attack vector is classified as network, with a low attack complexity and low privileges required. User interaction is necessary to trigger the exploit, as the victim must browse to the page containing the vulnerable field.
The potential impact includes low confidentiality and integrity impacts, with no availability impact. The affected products include Adobe Experience Manager versions prior to 6.5.24.0 and AEM Cloud Service versions prior to 2026.2.0.
Technical Analysis
The root cause of this vulnerability stems from improper handling of user input within form fields, allowing for the injection of JavaScript code. This type of vulnerability is commonly exploited through social engineering tactics, where users are tricked into interacting with malicious content.
Given the low attack complexity, the vulnerability can be exploited by attackers without requiring significant resources. The requirement for user interaction, however, does limit the attack vector to scenarios where users can be manipulated into visiting a malicious page or submitting forged data.
Organizations utilizing Adobe Experience Manager should conduct thorough testing of their applications to identify any vulnerable fields and implement appropriate input validation measures to mitigate the risk of XSS attacks.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized script execution in user browsers, which could lead to data theft, session hijacking, or other malicious activities. The blast radius of this vulnerability could be significant, especially in environments where Adobe Experience Manager is widely deployed.
Given the CVSS score of 5.4, organizations should address this vulnerability in their priority patch cycle. The low confidentiality and integrity impacts indicate that while the immediate risk may be moderate, the potential for exploitation in the wild necessitates a prompt response.
