What is CVE-2026-24741?
CVE-2026-24741 is a high-severity path traversal vulnerability in C4illin ConvertX, published on 27 Jan 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
