Summary
ScreenToGif is a screen recording tool. In versions from 2.42.1 and prior, ScreenToGif is vulnerable to DLL sideloading via version.dll . When the portable executable is run from a user-writable directory, it loads version.dll from the application directory instead of the Windows System32 directory, allowing arbitrary code execution in the user's context. This is especially impactful because ScreenToGif is primarily distributed as a portable application intended to be run from user-writable locations. At time of publication, there are no publicly available patches.
