## Affected

- craftcms cms: from 4.0.0-RC1, fixed in 4.17.5; from 5.0.0-RC1, fixed in 5.9.11

## Description

Craft CMS is a content management system (CMS). From version 4.0.0-RC1 to before version 4.17.5 and from version 5.0.0-RC1 to before version 5.9.11, the AssetsController->replaceFile() method has a targetFilename body parameter that is used unsanitized in a deleteFile() call before Assets::prepareAssetName() is applied on save. This allows an authenticated user with replaceFiles permission to delete arbitrary files within the same filesystem root by injecting ../ path traversal sequences into the filename. This could allow an authenticated user with replaceFiles permission on one volume to delete files in other folders/volumes that share the same filesystem root. This only affects local filesystems. This issue has been patched in versions 4.17.5 and 5.9.11.
