| summary: Arbitrary code execution via go.mod toolchain directive in cmd/go |
| description: |- |
| The go.mod toolchain directive, introduced in Go 1.21, can be leveraged to |
| execute scripts and binaries relative to the root of the module when the "go" |
| command was executed within the module. This applies to modules downloaded using |
| the "go" command from the module proxy, as well as modules downloaded directly |
| using VCS software. |
