Description

skilleton has improper input handling in repository/path processing

Summary

skilleton versions prior to 0.3.1 include security-related weaknesses in repository normalization and path handling logic.

Version 0.3.1 contains fixes and additional test coverage for these issues.

Affected Versions

<0.3.1

Patched Versions

>=0.3.1

Impact

In affected versions, crafted input could trigger unsafe or inefficient behavior in repository/path processing code paths.

0.3.1 mitigates this by:

  • replacing vulnerable parsing behavior with deterministic logic,
  • validating subpaths earlier before allocating git worktree resources,
  • adding stricter and broader regression tests around these flows.

Severity

Low to Moderate (project-maintainer assessed)

Mitigation

Upgrade to 0.3.1 or later.

Workarounds

No complete workaround is recommended other than upgrading.
