CVE-2025-54256
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 · uneditedDreamweaver Desktop versions 21.5 and earlier are affected by a Cross-Site Request Forgery (CSRF) 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 click on a malicious link, and 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 · high confidenceCross-Site Request Forgery (CSRF) vulnerability in Dreamweaver Desktop versions 21.5 and earlier allows authenticated users to be tricked into executing arbitrary code via malicious links. The scope is changed because the CSRF attack can leverage the application's trusted context to perform actions leading to code execution beyond the web application's normal boundaries.

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.
-
Confirm Adobe Dreamweaver installationCheck common installation directories: Windows typically at C:\Program Files\Adobe\Adobe Dreamweaver [version] or macOS at /Applications/Adobe Dreamweaver. On Windows, also verify via Add/Remove Programs or the registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for Dreamweaver entries.Affected if Adobe Dreamweaver Desktop is found installed on the system
-
Determine installed Dreamweaver versionWindows: Right-click the Dreamweaver executable, select Properties, then check the Details tab for Product Version. Alternatively, query the registry key HKLM\SOFTWARE\Adobe\Dreamweaver\InstallVersion. macOS: Right-click Adobe Dreamweaver in Applications, select Get Info, and check the Version field.Affected if The installed version cannot be determined or is below 21.6
-
Compare version against vulnerable rangeReview the version number obtained from the previous step. The affected range per the CVE is any version prior to 21.6, meaning versions 21.5 and earlier are vulnerable.Affected if Installed version is 21.5 or any earlier version number (for example, 21.4, 21.3, 20.x, etc.)
The user is affected if Adobe Dreamweaver Desktop version 21.5 or earlier is installed, as this version falls within the vulnerable range of < 21.6.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped21.6
Upgrade Dreamweaver Desktop to a version newer than 21.5; for interim protection, implement anti-CSRF tokens and validate Origin/Referer headers on sensitive operations.
Dreamweaver 21.6 or later
- Close Dreamweaver completely before updating
- Open the Adobe Creative Cloud desktop application on your system
- Navigate to the 'Apps' or 'All Apps' section in Creative Cloud
- Locate Adobe Dreamweaver in the installed applications list
- Click the 'Update' button next to Dreamweaver to install version 21.6 or later
- Wait for the update to download and install completely
- Launch Dreamweaver and verify the version number reflects 21.6 or newer
