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.
-
Verify Adobe Bridge is installedCheck for Adobe Bridge in your applications or program files folder. On Windows, look in C:\Program Files\Adobe\Adobe Bridge <version> or C:\Program Files (x86)\Adobe\Adobe Bridge <version>. On macOS, check /Applications/ for Adobe Bridge.appAffected if Adobe Bridge application exists on the system
-
Determine the installed Adobe Bridge versionOpen Adobe Bridge, then go to Help > About Adobe Bridge. The version number will be displayed in the about dialog. Alternatively, on Windows right-click the Bridge.exe file and select Properties > Details to view the File VersionAffected if Version displayed is 12.0 or 11.1.2 or earlier
-
Confirm version is within affected rangeCompare your installed version number to the affected ranges: any version below 11.1.3 (such as 11.1.2, 11.1.1, 11.0, 10.1.x, etc.) or exactly version 12.0Affected if Installed version is less than 11.1.3 or exactly equals 12.0
-
Check if user interaction vector appliesThis vulnerability requires a user to open a maliciously crafted file. Assess whether the user commonly opens files from untrusted sources, receives files via email, or downloads files from the internet into Adobe BridgeAffected if User opens untrusted or unexpected files in Adobe Bridge
