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 Creative Cloud Desktop Application is installedOpen Programs and Features (appwiz.cpl) or check the installation directory for Adobe Creative Cloud Desktop ApplicationAffected if The application appears in installed programs or its installation folder exists on the system
-
Locate the Creative Cloud Desktop executableNavigate to the default installation path (typically C:\Program Files\Adobe\Adobe Creative Cloud\CCLibrary or similar) and locate the main executable (CCLibrary.exe, CCL daemon.exe, or similar)Affected if The executable is present on the system
-
Retrieve the installed version from file propertiesRight-click the main Creative Cloud executable, select Properties, and check the Details tab for the File Version or Product VersionAffected if The version shown is 4.4.1.298 or earlier, or if no version number is displayed but the file exists in an older Creative Cloud installation folder
-
Compare version against affected rangeIf a version is displayed, compare it numerically to 4.4.1.298. Any version less than or equal to 4.4.1.298 falls within the affected rangeAffected if The installed version number is 4.4.1.298 or any version lower (for example, 4.4.0.0, 4.3.x.x, etc.)
-
Check for recent version updatesOpen the Creative Cloud desktop application and navigate to the preferences or about section to confirm if a newer version than 4.4.1.298 is reportedAffected if The application reports no update available or shows a version at or below 4.4.1.298
