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.
-
Locate Adobe Premiere Elements installationCheck common installation paths such as C:\Program Files\Adobe\Adobe Premiere Elements 2021\ or look for the application in Start Menu. The main executable is typically named Adobe Premiere Elements.exeAffected if Application is installed in any location
