MITRE ATT&CK
2 techniques across 2 tactics: Initial Access, Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires an authenticated low-privileged AEM account (author/contributor tier) with permission to submit content into one of the affected form fields - it is NOT unauthenticated. The stored payload only executes when a victim user actively navigates to the page containing the vulnerable field (UI:R), so successful attack also depends on a victim with browser access to that page, ideally a higher-privileged admin to make the scope change (S:C) impactful. Affected deployments are AEM 6.5.23 and earlier, AEM Cloud Service, and AEM 6.5 LTS. Limiting factors: two-party gating (attacker must be a provisioned author and a victim must view the content), low confidentiality/integrity impact and no availability impact, and no automatable mass-exploitation path. |
| Impact | This is a genuine-but-low-priority issue where the raw CVSS 5.4 (Medium) already reflects meaningful gating, and every corroborating signal points the same direction. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N shows a network-reachable flaw but double-gates exploitation: PR:L requires an authenticated low-privileged author/contributor account, and UI:R requires a victim to browse to the page hosting the malicious field. Impact is only C:L/I:L with A:N, consistent with a stored XSS that runs script in a victim's browser session rather than compromising the server. EPSS is very low at 0.20% (9th percentile), there is no CISA KEV listing, and no public exploit code is identified - so exploitation status is 'no public exploit identified at time of analysis.' No SSVC decision point is supplied in the input. Signals are consistent, not conflicting: low EPSS, no KEV, no POC, and a self-limiting CVSS all agree this is a real vulnerability worth patching in the maintenance cycle but not an emergency. The primary real-world risk is an insider or a compromised low-privilege authoring account persisting script that fires against higher-privileged admins in the same authoring environment (scope-change S:C). |
| Exploit ScenarioDerived | A low-privileged authenticated user (e.g., a content author) submits a payload containing malicious JavaScript into a vulnerable AEM form field, which is stored persistently. When another user - potentially a higher-privileged administrator - later browses to the page rendering that field, the script executes in their browser, enabling session token theft or actions in their context. No public proof-of-concept exploit code has been identified for this specific CVE. |

Alert meAnalysisAIv1 – Sep 26, 2026
Stored cross-site scripting in Adobe Experience Manager 6.5.23 and earlier (plus AEM Cloud Service and AEM 6.5 LTS) allows a low-privileged account - an author/contributor tier user with content submission rights - to persist malicious JavaScript into vulnerable form fields, which then executes in the browser of any user who views the affected page. Rated CVSS 5.4 Medium (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N), the flaw is gated by two conditions: the attacker must be an authenticated provisioned author, and a victim must actively browse to the poisoned page, meaning scope change to a higher-privileged browsing session is possible but requires victim interaction. There is no confirmed active exploitation (not in CISA KEV) and no public exploit code identified at time of analysis, and EPSS sits at just 0.20% (9th percentile), consistent with a genuine but low-priority issue; Adobe has published advisory APSB25-115.
RemediationAI
Apply the fix identified in Adobe's advisory APSB25-115 (https://helpx.adobe.com/security/products/experience-manager/apsb25-115.html), upgrading Experience Manager beyond the affected 6.5.23-and-earlier codebase to the patched release line the bulletin specifies, and apply the corresponding fix to AEM Cloud Service and AEM 6.5 LTS deployments. Because exploitation requires an authenticated low-privileged author account, tightening compensating controls around that tier meaningfully reduces exposure: restrict and regularly review which accounts hold author/contributor content-submission permissions, and separate authoring from publish access so contributor accounts cannot reach privileged administrative views. Enforce a Content Security Policy on rendered AEM pages to blunt script execution - noting that CSP can break legitimate inline SDK and custom component behavior and requires testing. Enable server-side output encoding/sanitization for custom form components and disable or restrict non-essential custom form fields and editable templates until patched, accepting that this reduces authoring flexibility. A WAF or reverse-proxy rule filtering script payloads in form submissions offers temporary relief but is trivially bypassable with encoding tricks and should not be treated as a substitute for patching.

Technical ContextAI · show details
The root cause is CWE-79 (Improper Neutralization of Input During Web Page Generation, i.e., stored/persistent cross-site scripting) in Adobe Experience Manager's form-field handling. AEM is a Java-based content management and digital experience platform whose authoring tier stores contributor-submitted content in the JCR repository and later renders it through HTL/Sightly components served to the publish tier. The vulnerability arises because user-supplied form field values are persisted without adequate output encoding or sanitization, so script markup survives storage and is emitted into the HTML response for subsequent visitors. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N describes network-reachable exploitation with low attack complexity that nevertheless requires a valid low-privileged account (PR:L, an AEM author/contributor), and requires the victim to take the action of navigating to the crafted page (UI:R). The Scope:Changed (S:C) component reflects that the injected script runs in the security context of a different user - typically an administrator or other privileged AEM user browsing the content - so although direct confidentiality and integrity impact is rated Low and availability impact None, the compromise crosses a privilege boundary. Exact affected components map to CPE entries for adobe:experience_manager (all versions), the aem_cloud_service edition, and the 6.5 lts release channel.

DescriptionCVE.org
Adobe Experience Manager versions 6.5.23 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.
