The advisory

Trudesk through 1.2.11 contains a path traversal vulnerability that allows administrators to delete arbitrary files by supplying encoded traversal sequences to DELETE /api/v1/backup/:backup. Attackers can also pass unvalidated file values to POST /api/v1/backup/restore to restore archives from, or extract to, paths outside the intended directories.

Check your whole app

Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
