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 · unedited
Dreamweaver Desktop versions 21.7 and earlier are affected by a Dependency on Vulnerable Third-Party Component vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. Scope is changed.

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 · moderate confidence

Dreamweaver Desktop versions 21.7 and earlier depend on a vulnerable third-party component that could allow arbitrary code execution when a user opens a malicious file. The scope is changed, indicating the vulnerability impacts components beyond the third-party library itself.

MitigationUpdate Dreamweaver Desktop to a version newer than 21.7 once Adobe releases a patch. Until then, avoid opening untrusted or unexpected files in Dreamweaver.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Dreamweaver Desktop is installed
    Check your system for Adobe Dreamweaver installation. On Windows, look in Program Files/Adobe or check Programs and Features. On macOS, check /Applications for Dreamweaver.app.
    Affected if Dreamweaver Desktop is present on the system
  2. Determine installed Dreamweaver version
    Open Dreamweaver and go to Help > About Adobe Dreamweaver, or right-click the Dreamweaver executable and select Properties > Details to view the version number.
    Affected if Version displayed is 21.7 or any version lower than 21.8
  3. Assess file opening behavior
    Determine whether you open files from untrusted or unknown sources in Dreamweaver, as the vulnerability is exploited through opening a malicious file.
    Affected if You routinely open files from untrusted or unknown sources in Dreamweaver

If Dreamweaver Desktop is installed and the version is 21.7 or earlier, the environment is affected by this vulnerability.

Upgrade available Upgrade to 21.8 or later
Fixed in 21.8
Interim mitigation

Update Dreamweaver Desktop to a version newer than 21.7 once Adobe releases a patch. Until then, avoid opening untrusted or unexpected files in Dreamweaver.

Recommended fix High confidence

21.8

  1. Open Adobe Creative Cloud desktop application or navigate to the Adobe Dreamweaver download page at helpx.adobe.com
  2. Locate Adobe Dreamweaver in your installed applications
  3. Check the current version (Help > About Dreamweaver) to confirm it is below 21.8
  4. Initiate the update through Adobe Creative Cloud or download Dreamweaver version 21.8 directly from Adobe
  5. Install the update and restart Dreamweaver
  6. Verify the installed version is 21.8 or later by checking Help > About Dreamweaver
Caveat Adobe minor version updates typically do not introduce breaking changes; ensure any site-specific extensions are compatible with version 21.8
