Exploitation Conditions

Exploitation requires an authenticated account with low privileges sufficient to submit or edit the affected AEM form fields (PR:L), so it is not exploitable by anonymous outsiders against a default hardened deployment. The stored payload only triggers when a victim navigates to the page containing the vulnerable field (UI:R), meaning a valid content-authoring or form-input path must exist and be reachable by a victim. Affected deployments are AEM 6.5.23 and earlier, AEM Cloud Service, and AEM 6.5 LTS. Limiting factors: required prior authentication, required victim page visit, and impact confined to the browser (C:L/I:L, no A) rather than server compromise.

Impact

This is a genuine but low-priority issue. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) scores 5.4 (MEDIUM) and is internally consistent with a stored XSS: network-reachable, low complexity, but double-gated by requiring both low-privilege authentication (PR:L) and victim interaction (UI:R - a victim must browse to the affected page). Impact is capped at C:L/I:L with no availability effect. Exploitation signals are weak and mutually reinforcing: EPSS is 0.25% (15th percentile), there is no CISA KEV listing, and no public POC is referenced - no public exploit identified at time of analysis. No SSVC decision data was provided. There are no conflicting signals: the low EPSS aligns with the modest CVSS and the lack of KEV/POC. Net assessment: a real defect worth patching in the normal Adobe security cycle, not an emergency; the enterprise footprint of AEM raises attention but the authentication + user-interaction gating and low impact keep real-world priority LOW.

Exploit ScenarioDerived

A low-privileged authenticated AEM user (e.g., a content author or form editor) injects a malicious script payload into a vulnerable form field. When a higher-privileged user or another victim later browses to the page rendering that field, the stored JavaScript executes in their browser, enabling session/cookie theft or actions in the victim's AEM context. No public proof-of-concept is known, and exploitation requires the victim to visit the affected page.

AnalysisAIv1 – Sep 26, 2026

Adobe Experience Manager 6.5.23 and earlier, including the Cloud Service and 6.5 LTS tracks, can be abused by an authenticated low-privileged user to store malicious JavaScript in vulnerable form fields, which then executes in the browser of a victim who later visits the affected page and produces limited confidentiality and integrity impact in that session. Exploitation requires prior low-privilege authentication and a victim page visit, no public exploit code or CISA KEV entry was identified at time of analysis, and the EPSS score is 0.25% at the 15th percentile, making this a genuine but low-priority issue.

RemediationAI

Patch available per vendor advisory: consult Adobe advisory APSB25-115 at https://helpx.adobe.com/security/products/experience-manager/apsb25-115.html for the fixed AEM release and apply it; AEM Cloud Service customers should follow the advisory guidance for managed service remediation, and on-premises or LTS administrators should upgrade beyond the affected 6.5.23 and earlier line as directed. If immediate patching is not possible, restrict form-field authoring or submission privileges to trusted low-privileged users, review and remove any previously injected scripts from AEM form content, and consider a content security policy or WAF rule that blocks inline script execution; these measures reduce exposure but do not replace the vendor fix, and CSP or WAF tuning may break legitimate AEM functionality if not scoped carefully.

Technical ContextAI · show details

This is a CWE-79 improper neutralization of input during web page generation flaw, specifically a stored cross-site scripting issue in Adobe Experience Manager form-field handling. AEM is an enterprise content management and digital experience platform, and the affected CPE entries identify Adobe Experience Manager generally, AEM Cloud Service, and AEM 6.5 LTS, with the 6.5.23 and earlier release line vulnerable. The CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N vector indicates network reachability, low privileges required, victim user interaction, scope change, and limited browser-side confidentiality and integrity impact with no availability impact; because the payload is stored server-side rather than reflected only once, it can persist and be delivered to later visitors.
