In `internal/defaultcodesamples/defaultcodesamples.go`, the code creates a temporary file using `os.TempDir()` with a hardcoded filename `defaultcodesamples.js`. This is predictable and could lead to a race condition or symlink attack if an attacker can create this file before the program does. The file is written with `0o644` permissions and then executed via `exec.Command`. Signed-off-by: tomaioo <203048277+tomaioo@users.noreply.github.com>

Severity:
Medium| File:internal/defaultcodesamples/defaultcodesamples.go:L38In
internal/defaultcodesamples/defaultcodesamples.go, the code creates a temporary file usingos.TempDir()with a hardcoded filenamedefaultcodesamples.js. This is predictable and could lead to a race condition or symlink attack if an attacker can create this file before the program does. The file is written with0o644permissions and then executed viaexec.Command.Solution
Use
os.CreateTemporos.MkdirTempto create a temporary directory with a random name, then write the file there. This prevents predictable path attacks. Also ensure the temporary directory is cleaned up after execution.Changes
