DescriptionCVE.org

Adobe Experience Manager versions 6.5.24, LTS SP1, 2026.04 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. Scope is changed.

AnalysisAI

Stored Cross-Site Scripting in Adobe Experience Manager allows a low-privileged authenticated attacker to inject persistent malicious JavaScript into vulnerable form fields, which subsequently executes in any victim's browser upon visiting the affected page. Affected versions include AEM 6.5.24, LTS SP1, and 2026.04 and earlier. The scope-changed CVSS designation reflects the cross-context impact typical of stored XSS - compromising the victim's browser session rather than just the server-side application. No public exploit code or CISA KEV listing has been identified at time of analysis.

Technical ContextAI

Adobe Experience Manager (AEM) is an enterprise content management platform used for building and managing web content and digital assets. The vulnerability is rooted in CWE-79 (Improper Neutralization of Input During Web Page Generation), meaning user-supplied input containing script tags or event handlers is stored server-side without adequate sanitization and later reflected into rendered HTML without proper output encoding. The CVSS Scope:Changed attribute confirms the exploit crosses the trust boundary from the AEM application context into the victim's browser context, enabling session hijacking, credential theft, or DOM manipulation. Affected CPE data from EUVD covers Adobe Experience Manager versions up to and including 2026.04, encompassing the 6.5.x Long Term Support branch (SP1) and the cloud/continuous delivery track.

RemediationAI

The primary remediation is to apply the patch or updated version documented in Adobe security advisory APSB26-56, available at https://helpx.adobe.com/security/products/experience-manager/apsb26-56.html. The exact fixed version number is not independently confirmed in the available input data beyond the advisory reference - consult the advisory directly to obtain the specific target version for your AEM track (6.5.x LTS or cloud continuous delivery). As a compensating control prior to patching, restrict write access to AEM form fields and authored content areas to the minimum set of trusted users, reducing the pool of accounts that could introduce stored payloads. Deploying a Web Application Firewall rule to inspect and block script injection patterns in form submissions can reduce exposure but carries a risk of false positives affecting legitimate content authoring workflows. Content Security Policy (CSP) headers configured to restrict inline script execution can limit the impact of any stored XSS that is not yet remediated, though AEM's rich authoring environment may require careful policy tuning to avoid breaking functionality.
