This is the netplay fork of sciaschi/CBFD-Recompiled. Its netplay code talks to other computers over the internet (host/src/netplay/, the packets and the session in host/src/netplay/net/), so a flaw there could matter to the people playing.
Please report a security problem privately, not as a public issue: use Report a vulnerability on this repository's Security tab. Say what an attacker could do, and how (a packet, a join code, a recording or save state, a release file).
Problems in the rest of the game belong upstream. Only the latest release is supported.
