The record
The SCP middleware in `charm.land/wish/v2` is vulnerable to path traversal attacks. A malicious SCP client can read arbitrary files from the server, write arbitrary files to the server, and create directories outside the configured root directory by sending crafted filenames containing `../` sequences over the SCP protocol.
