Description
AI Translation Available
gopls by default communicates via pipe. However, -port and -listen flags are supported as means of debugging.
If -listen is given a value without an explicit host (e.g. :8080), or -port is used, gopls will listen on 0.0.0.0.
As a result, users might inadvertently cause gopls to bind 0.0.0.0.
This can allow a malicious party on the same network to execute code arbitrarily via gopls.
