gopls: gopls by default communicates via pipe
CVE-2026-42503 is fixed in gopls on 1 platform by DEBIAN-CVE-2026-42503 (version 2:0.22.0+ds-1), released May 6, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
