However, -port and -listen flags are supported as means of debugging.\nIf -listen is given a value without an explicit host (e.g. :8080), or -port is used, gopls will listen on 0.0.0.0. \nAs a result, users might inadvertently cause gopls to bind 0.0.0.0.\nThis can allow a malicious party on the same network to execute code arbitrarily via gopls.","published":"2026-05-06T17:16:23.000Z","lastModified":"2026-10-26T19:10:00.000Z","status":"Analyzed","sourceIdentifier":"security@golang.org","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-1327"],"affected":["golang/gopls"],"epss":{"score":0.00212,"percentile":0.11446,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.21%).
