CVE-2025-66449

ConvertX has Path Traversal that leads to Arbitrary File Write and Arbitrary Code Execution

ConvertXis a self-hosted online file converter. In versions prior to 0.16.0, the endpoint /upload allows an authenticated user to write arbitrary files on the system, overwriting binaries and allowing code execution. The upload function takes file.name directly from user supplied data without doing any sanitization on the name thus allowing for arbitrary file write. This can be used to overwrite system binaries with ones provided from an attacker allowing full code execution. Version 0.16.0 contains a patch for the issue.
