DescriptionNVD

Adobe Experience Manager Forms JEE versions LTS SP1, 6.5.24.0 and earlier are affected by a reflected Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this vulnerability to inject malicious scripts into a web page, potentially gaining elevated access or control over the victim's account or session. Exploit depends on conditions beyond the attacker's control. Exploitation of this issue requires user interaction in that a victim must visit a maliciously crafted URL or interact with a compromised web page. Scope is changed.

AnalysisAI

Reflected Cross-Site Scripting in Adobe Experience Manager Forms JEE (LTS SP1 and 6.5.24.0 and earlier) allows remote unauthenticated attackers to execute arbitrary script in a victim's browser session, potentially hijacking accounts or escalating privileges within the AEM Forms environment. The Scope:Changed flag in the CVSS vector indicates the impact extends beyond the vulnerable component, which combined with High confidentiality and integrity impacts yields a CVSS of 8.0. …

Vulnerability AssessmentAI

Exploitation Exploitation requires (1) the targeted organization to be running Adobe Experience Manager Forms JEE LTS SP1 or 6.5.24.0 or earlier with the vulnerable reflective endpoint reachable by the victim's browser, (2) user interaction - specifically, an authenticated AEM Forms user (ideally an administrator, to realize the Scope:Changed privilege crossover) must visit the attacker-crafted URL or a page that triggers the reflective request, and (3) per Adobe's own description, additional conditions beyond the attacker's control must align, consistent with the CVSS High attack complexity rating (AC:H) - likely involving specific browser, session, or input-parsing states. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS vector AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:N reveals a more nuanced picture than the raw 8.0 score suggests: exploitation requires both High attack complexity (Adobe notes 'Exploit depends on conditions beyond the attacker's control') and User Interaction (the victim must click a crafted link or visit a poisoned page), which materially limits drive-by mass-exploitation potential. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a URL targeting a vulnerable reflective endpoint on the victim organization's AEM Forms JEE server with a JavaScript payload in a request parameter, then delivers it via phishing email or a watering-hole site frequented by AEM administrators. When a logged-in AEM Forms administrator clicks the link, their browser executes the attacker's script under the AEM origin and, because the scope is Changed, in a higher-privilege context - allowing the attacker to exfiltrate the admin session token, submit form-management API calls on the admin's behalf, or pivot to stored content. …
Remediation Patch available per vendor advisory APSB26-57 (https://helpx.adobe.com/security/products/aem-forms/apsb26-57.html); apply the fixed AEM Forms JEE Service Pack referenced in that bulletin as the primary remediation - exact post-LTS-SP1 / post-6.5.24.0 fix build should be taken from the Adobe advisory itself. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all Adobe Experience Manager Forms JEE deployments running LTS SP1, 6.5.24.0 or earlier; brief security and development teams on vulnerability scope and risks. …
