DescriptionNVD

Adobe Experience Manager Forms JEE versions LTS SP1, 6.5.24.0 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an 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, potentially gaining elevated access or control over the victim's account or session. Scope is changed.

AnalysisAI

Stored cross-site scripting in Adobe Experience Manager Forms JEE LTS SP1 and 6.5.24.0 and earlier allows remote unauthenticated attackers to inject malicious JavaScript into vulnerable form fields that executes in victims' browsers when they visit the affected page. The scope-changed CVSS 9.3 reflects that the injected script can pivot beyond the vulnerable component to compromise the victim's authenticated session or account. …

Vulnerability AssessmentAI

Exploitation The attacker must be able to submit data into a vulnerable form field of an AEM Forms JEE deployment running LTS SP1 or 6.5.24.0 or earlier - per CVSS PR:N this submission step itself requires no authentication. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals are mixed and warrant careful interpretation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker submits a crafted form on a public-facing AEM Forms JEE page, embedding a JavaScript payload in a field whose contents are later rendered to back-office reviewers or administrators. When a privileged user opens the form in their browser, the stored payload executes in their session context and exfiltrates session cookies or invokes administrative API calls on their behalf, pivoting the compromise from the form component into the broader AEM environment (scope change). …
Remediation Patch available per vendor advisory APSB26-57 at https://helpx.adobe.com/security/products/aem-forms/apsb26-57.html - upgrade AEM Forms JEE to the fixed version listed in that bulletin (exact fixed version is not enumerated in the input data and should be taken from the Adobe advisory). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all Adobe Experience Manager Forms JEE deployments and identify instances running version 6.5.24.0 or earlier; assess external user exposure to web forms. …
