Flextype CMS through 1.0.0-alpha.3 Path Traversal via Entries REST API
Flextype CMS through 1.0.0-alpha.3 fails to properly validate id and new_id parameters in the Entries REST API, allowing API token holders to read, create, or overwrite files outside the entries directory. Attackers can use traversal sequences in API requests to escape the project entries directory and manipulate arbitrary files and directories on the filesystem.
