Description

ConvertXis a self-hosted online file converter. In versions prior to 0.17.0, the `POST /delete` endpoint uses a user-controlled `filename` value to construct a filesystem path and deletes it via `unlink` without sufficient validation. By supplying path traversal sequences (e.g., `../`), an attacker can delete arbitrary files outside the intended uploads directory, limited only by the permissions of the server process. Version 0.17.0 fixes the issue.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
