Title
Gvisor-tap-vsock: gvisor-tap-vsock: unathenticated arbitrary file deletion on the host via /expose
Summary
A path traversal vulnerability was found in gvproxy, the network forwarder provided by the gvisor-tap-vsock package. The unauthenticated /services/forwarder/expose endpoint does not validate the caller-supplied socket path, allowing an attacker to delete arbitrary files on the host system.
Severity
