What version of Go are you using (go version)?

Go 1.20, via https://go.dev/play/

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

https://go.dev/play/

What did you do?

package main

import (
	"fmt"

	"golang.org/x/sys/execabs"
)

func main() {
	fmt.Println(execabs.Command("this-command-does-not-exist").Start())
}

What did you expect to see?

An error message should complain that the executable was not found in the current PATH, or something along those lines. The os/exec equivalent code returns this error:

exec: "this-command-does-not-exist": executable file not found in $PATH

What did you see instead?

The error reported is:

this-command-does-not-exist resolves to executable in current directory (./this-command-does-not-exist)

(This is not true, there is no such file in the current directory)
