Description
DumbAssets through 1.0.11 contains a path traversal vulnerability in the POST /api/delete-file endpoint and filesToDelete array parameters that allows unauthenticated attackers to delete arbitrary files by supplying ../ sequences that bypass directory boundary validation. Attackers can exploit the optional and disabled-by-default authentication control to traverse outside the intended application directory and delete critical files such as server.js or package.json, causing complete denial of service.
