  "title": "gopls: gopls by default communicates via pipe",
  "description": "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.\u00A0 As a result, users might\u00A0inadvertently cause gopls to bind 0.0.0.0. This can allow a\u00A0malicious party on the same network to execute code arbitrarily via gopls.",
