GHSA-pf2q-pxhf-hgmw: n8n: Path-Confinement Bypass in computer-use search_files Allows Reading Files Outside the Base Directory

The component @n8n/computer-use file-search tool confined searches to a configured base directory. A crafted search pattern could bypass the confinement check and expand to locations outside that directory, causing the tool to return the names and contents of files anywhere the daemon’s OS user could read. Any deployment where an actor could influence the tool’s search input was affected; the result was disclosure of arbitrary local files outside the intended sandbox.
