### Impact This vulnerability affects deployments of FreeImage that involve decoding or processing malicious source .webp files. If you only process your own trusted files, this should not affect you, but **you should remove FreeImage from your project, as it is not maintained and presents a massive security risk**. If you are using FreeImage via ImageResizer.Plugins.FreeImage, please utilize [Imageflow](https://github.com/imazen/imageflow) or [Imageflow.Server](https://github.com/imazen/imageflow-dotnet-server) instead, or upgrade to ImageResizer 5 and use ImageResizer.Plugins.Imageflow (enable Prereleases on NuGet to access). FreeImage relies on Google's [libwebp](https://github.com/webmproject/libwebp) library to decode .webp images, and is affected by the recent zero-day out-of-bounds write vulnerability [CVE-2023-4863](https://nvd.nist.gov/vuln/detail/CVE-2023-4863) and https://github.com/advisories/GHSA-j7hp-h8jx-5ppr. The libwebp vulnerability also affects Chrome, Android,...
