Summary

This pull request rejects tar symlink targets that point outside the extracted archive root during workspace hydrate and restore flows.

  • add strict symlink-target validation to tar_utils for hydrate paths while keeping the general tar helpers' default behavior unchanged
  • enable the stricter validation in UnixLocal, Docker, and tar-based extension backends before they materialize a workspace archive
  • add regression coverage for strict tar validation plus UnixLocal and Vercel hydrate paths

Compatibility change: If a user’s sandbox snapshot/workspace contains symlinks intentionally pointing to system paths (e.g., /usr/bin/python, certain toolchain paths, or host mount points), then after hydrate/restore these will change from “restorable” to “refused to restore.”

Test plan

  • uv run pytest tests/sandbox/test_tar_utils.py tests/sandbox/test_extract.py tests/extensions/sandbox/test_vercel.py
  • bash .agents/skills/code-change-verification/scripts/run.sh

Issue number

Closes#3093

Checks

  • I've added new tests (if relevant)
  • I've added/updated the relevant documentation
  • I've run make lint and make format
  • I've made sure tests pass

Summary

This pull request rejects tar symlink targets that point outside the extracted archive root during workspace hydrate and restore flows.

  • add strict symlink-target validation to tar_utils for hydrate paths while keeping the general tar helpers' default behavior unchanged
  • enable the stricter validation in UnixLocal, Docker, and tar-based extension backends before they materialize a workspace archive
  • add regression coverage for strict tar validation plus UnixLocal and Vercel hydrate paths

Compatibility change: If a user’s sandbox snapshot/workspace contains symlinks intentionally pointing to system paths (e.g., /usr/bin/python, certain toolchain paths, or host mount points), then after hydrate/restore these will change from “restorable” to “refused to restore.”

Test plan

  • uv run pytest tests/sandbox/test_tar_utils.py tests/sandbox/test_extract.py tests/extensions/sandbox/test_vercel.py
  • bash .agents/skills/code-change-verification/scripts/run.sh

Issue number

Closes#3093

Checks

  • I've added new tests (if relevant)
  • I've added/updated the relevant documentation
  • I've run make lint and make format
  • I've made sure tests pass
