Flextype CMS versions up to 1.0.0-alpha.3 are vulnerable due to inadequate validation of the id and new_id parameters in the Entries REST API, enabling API token holders to exploit directory traversal vulnerabilities. This flaw allows unauthorized access to read, create, or overwrite files outside the intended entries directory, potentially compromising the integrity of the filesystem. Organizations using this CMS should prioritize patching to mitigate the risk of unauthorized file manipulation and data exposure.

Original NVD Description

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.
