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 | Requires an authenticated low-privileged AEM account (PR:L) plus victim user interaction (UI:R) - the victim must visit a crafted URL or interact with a manipulated web page for the DOM-based script to execute. Affects Adobe Experience Manager 6.5.23 and earlier, including AEM Cloud Service and AEM 6.5 LTS. Exploitation is client-side only (browser context), yielding limited confidentiality and integrity impact and no availability impact; there is no server-side code execution. The combined authentication and user-interaction requirements meaningfully limit realistic exploitation. |
| Impact | This is a genuinely low-priority issue despite affecting a widely-deployed enterprise platform. The CVSS 3.1 base score is 5.4 (Medium), and the vector CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N reflects meaningful gating: exploitation requires an authenticated low-privileged account (PR:L) AND victim user interaction (UI:R), with only Low confidentiality and Low integrity impact and no availability impact. EPSS reinforces low real-world risk at 0.20% (9th percentile), among the lowest exploitation probabilities. It is not in CISA KEV and no public exploit code has been identified. All signals are consistent and non-conflicting: a client-side DOM-based XSS that is double-gated (auth + user click) with limited impact. The scope-change flag (S:C) - script executing in the victim's browser origin - is the main reason it clears the Medium threshold rather than landing lower. This is a routine hygiene fix, not an urgent priority. |
| Exploit ScenarioDerived | A low-privileged authenticated AEM user crafts a malicious URL or manipulated page that abuses a client-side DOM sink; when a victim (e.g., an author or admin) visits it, attacker-controlled JavaScript runs in the victim's browser within the AEM origin, enabling session/context abuse such as reading page content or performing limited actions as the victim. No public proof-of-concept exploit is available at time of analysis, and Adobe rates impact as Low across confidentiality and integrity. |

Alert meAnalysisAIv1 – Sep 25, 2026
DOM-based cross-site scripting (XSS) in Adobe Experience Manager 6.5.23 and earlier lets an authenticated low-privileged attacker execute malicious scripts in a victim's browser, but only if the victim visits a crafted URL or interacts with a manipulated page. The flaw is client-side only, yielding limited confidentiality and integrity impact with no availability impact. No public exploit code has been identified (EPSS 0.20%, 9th percentile), and the combined authentication and user-interaction requirements significantly limit real-world exploitation.
RemediationAI
Patch available per vendor advisory: apply the update specified in Adobe security advisory APSB25-115 (https://helpx.adobe.com/security/products/experience-manager/apsb25-115.html). Adobe has released updates for AEM 6.5 and AEM Cloud Service; upgrade to the latest version that contains the fix. For AEM 6.5 LTS, follow the advisory's guidance for the patched release. Since exploitation requires an authenticated low-privileged account and victim interaction, additional compensating controls include enforcing a strict Content Security Policy (CSP) to block inline script execution, though this may break legitimate functionality. Restricting user permissions and monitoring for suspicious URLs can also reduce risk, but patching remains the primary remediation.

Technical ContextAI · show details
This is a DOM-based XSS vulnerability (CWE-79) in Adobe Experience Manager, a widely used enterprise content management platform. DOM-based XSS occurs when client-side JavaScript processes attacker-controlled data-such as URL fragments or parameters-and writes it to the DOM without proper sanitization or escaping, leading to script execution in the victim's browser context. The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) confirms network attack, low privileges required (authenticated), user interaction required, and scope change because the vulnerable component impacts resources beyond its security scope. Affected products include AEM 6.5.23 and earlier, AEM Cloud Service, and AEM 6.5 LTS, as indicated by CPE entries. The vulnerability does not allow server-side code execution; the impact is confined to the client browser.

AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
Network-delivered DOM XSS needs a low-priv authenticated actor (PR:L) and victim click (UI:R); script escaping into the browser origin gives S:C with Low C/I and no A.
