CVE-2024-26039
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAdobe Experience Manager versions 6.5.20 and earlier Answer: are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability. This vulnerability could allow an attacker to execute arbitrary JavaScript code in the context of the victim's browser session. Exploitation of this issue requires user interaction, such as convincing a victim to click on a specially crafted link or to submit a form that triggers the vulnerability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAdobe Experience Manager versions 6.5.20 and earlier contain a DOM-based Cross-Site Scripting (XSS) vulnerability where malicious JavaScript can be injected through the DOM manipulation of user-supplied input. This allows attackers to execute arbitrary JavaScript in the victim's browser context when they interact with specially crafted links or forms.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Adobe Experience Manager versionAccess the AEM system console at /system/console/product.json or view the version from the AEM Welcome page (select Tools > Operations > Web Console, then look at the Product Information section)Affected if The installed version is 6.5.20 or earlier, or falls below version 2024.5
-
Identify the exact product version numberIn the AEM Web Console, navigate to the Product Information page or check the crx-quickstart/conf folder for version.info fileAffected if The version displayed is lower than 6.5.21 or lower than 2024.5
-
Determine the release trackCheck whether the installation follows the 6.5.x LTS track or the newer 2024.x rapid release track by reviewing the version number format in the product infoAffected if Running on 6.5.x track below 6.5.21, or on 2024.x track below 2024.5
You are affected if your AEM installation is version 6.5.20 or earlier on the 6.5.x LTS track, or any version below 2024.5 on the 2024.x release track.

dbcve · scoped6.5.212024.5
Upgrade Adobe Experience Manager to version 6.5.21 or later to obtain the patch. Implement Content Security Policy (CSP) headers and validate/sanitize all user inputs on the client side to prevent DOM-based XSS execution.
AEM 6.5.21 (for 6.5.x line) or AEM 2024.5 (for 2024.x line)
- 1. Identify the current Adobe Experience Manager version in your environment
- 2. Determine which release line you are on (6.5.x legacy line or 2024.x newer line)
- 3. If on the 6.5.x line: download and plan upgrade to AEM 6.5.21 or later
- 4. If on the 2024.x line: download and plan upgrade to AEM 2024.5 or later
- 5. Backup your current AEM instance and content repositories before upgrading
- 6. Test the upgrade in a staging or development environment first
- 7. Validate that custom code and integrations work correctly after upgrade
- 8. Deploy the upgraded version to production
