Exploitation Conditions

Exploitation requires an authenticated low-privileged account on Adobe Experience Manager (PR:L) with the ability to submit data into the affected form fields, plus a victim who subsequently browses to the page rendering the stored payload (UI:R). Affected builds are AEM 6.5 up to and including 6.5.25 and AEM 6.5 LTS up to and including SP3. The limiting factors - required authentication, required victim interaction, and the fact that impact is confined to script execution in a browser (no direct server confidentiality/integrity loss beyond the injected context) - reduce realistic risk; the exposure is greatest on author/multi-tenant instances where content-contributor accounts are not fully trusted.

Impact

This is a moderate-severity stored XSS (CWE-79) in Adobe Experience Manager, scored CVSS 5.4 by Adobe PSIRT. The CVSS vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) indicates network reach and low attack complexity, but two factors materially cap real-world risk: the attacker must already hold low-privileged authenticated access (PR:L), and a victim must browse to the page containing the injected field (UI:R). The scope change (S:C) reflects that injected script executes in the victim's browser context rather than only the vulnerable component, which is typical and expected for stored XSS. No EPSS score, CISA KEV listing, or public POC was provided in the intelligence, so there is no evidence of active exploitation or weaponization - this appears to be a vendor-disclosed issue rather than an urgent in-the-wild threat. Net assessment: a legitimate but not emergency priority. It is more relevant for multi-tenant or author-instance AEM deployments where low-privileged content contributors are not fully trusted; in locked-down single-tenant author environments the authenticated + user-interaction prerequisites meaningfully reduce likelihood. Missing data to note explicitly: no EPSS probability and no KEV/POC signals were supplied, so exploitation likelihood cannot be quantified from the input.

Exploit ScenarioDerived

A low-privileged authenticated user (e.g., a content contributor on an AEM author instance) injects malicious JavaScript into a vulnerable form field. The payload is stored, and when another user - such as a reviewer or administrator - browses to the page rendering that field, the script executes in their browser, potentially hijacking their session or performing actions in their context. No public exploit code was identified in the provided intelligence.

AnalysisAIv1 – Oct 14, 2026

Stored cross-site scripting in Adobe Experience Manager 6.5 (through 6.5.25) and AEM 6.5 LTS (through SP3) allows an authenticated, low-privileged user to persist malicious JavaScript into vulnerable form fields, which then executes in the browser of any victim who later views the page rendering that content. The assessed CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N for a base score of 5.4, meaning the attacker must hold a valid low-privileged account and the victim must actively browse to the injected page; the scope is changed because the script runs in the victim's browser context rather than the server's. Exposure is greatest on author or multi-tenant instances where content-contributor accounts are not fully trusted, and no public exploit identified at time of analysis - no CISA KEV entry or proof-of-concept code is present in the available intelligence, and no EPSS score was supplied.

RemediationAI

Apply the fix published in Adobe security bulletin APSB26-152 (https://helpx.adobe.com/security/products/experience-manager/apsb26-152.html), which is the vendor's authoritative source; the exact patched build number was not included in the supplied intelligence, so the fixed version must be read from that bulletin rather than assumed, and upgrade the affected 6.5 line past 6.5.25 and the 6.5 LTS line past SP3 accordingly. Where immediate patching is not possible, the highest-value compensating control is to restrict and review the set of accounts holding form-submission or content-contributor privileges, since the attack requires an authenticated low-privileged account - the trade-off is reduced authoring throughput for content teams - and to segregate multi-tenant or third-party contributor accounts so untrusted users cannot author pages that render to privileged staff. Additional interim measures include enforcing a strict Content-Security-Policy on AEM author and publish domains to block inline script execution (trade-off: legitimate inline scripts in custom components and some Granite/Coral UI behavior may break and require allowlisting), deploying Dispatcher or WAF rules that filter or encode script-bearing payloads in form POST bodies and query strings (trade-off: false positives can block legitimate rich-text content and require tuning), and disabling or hardening any custom form components that echo field values without context-aware output encoding. Restricting the AEM author interface to trusted networks or VPN reduces the victim pool for stored payloads but does not remove the underlying code flaw, and no mitigations should be treated as a substitute for applying the vendor fix once the patched version is confirmed.

Technical ContextAI · show details

The root cause is CWE-79 (Improper Neutralization of Input During Web Page Generation), specifically the stored/persistent variant, in Adobe Experience Manager's form-handling components. AEM is a Java-based enterprise content management platform whose authoring and publishing tiers render user-supplied form field content back into HTML without sufficient output encoding for the execution context, so attacker-controlled markup survives server-side storage and is re-emitted to subsequent visitors. The CVSS scope change (S:C) reflects that the injected script executes in the victim's browser origin, escaping the security authority of the vulnerable component, but the confidentiality and integrity impacts are rated Low (C:L/I:L/A:N) because the effect is limited to script execution in the rendered page rather than direct server-side data loss or full session compromise in the general case. The privilege requirement (PR:L) is the key structural constraint: the attacker does not need administrative rights, only the ability to submit data into the affected fields, which is a normal capability for content contributors, form designers, and similar roles on authoring instances. The EUVD data resolves the vulnerable surface to the 6.5 line (0 through 6.5.25) and the 6.5 Long-Term Support line (0 through 6.5 LTS SP3), and the only authoritative patch reference is Adobe security bulletin APSB26-152. No CPE strings were provided in the source data, so exact platform/host CPE matching was not possible; the EUVD version ranges are the authoritative scope statement.
