NVD Description

Note: Versions mentioned in the description apply only to the upstream golang1.25-docs package and not the golang1.25-docs package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
