> +
+An on-path attacker is present between the QUIC client and server, and an
+endpoint is required to send packets through this attacker to establish
+connectivity on a given path.
+An on-path attacker can:
+- Inspect packets
+- Modify unencrypted packet headers
+- Inject new packets
+- Delay packets
+- Drop packets
+An on-path attacker cannot:
+- Modify encrypted packet payloads

Updated this a bit, I suspect further discussion will also be in the security properties of short/long headers.
