Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

Installation context

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Most static findings are false positives from Markdown code fences, tmux syntax, expected dotfile paths, and documented public URLs. The fixed /tmp cache examples and pane-content persistence setting are real local privacy and integrity concerns. No prompt injection or data-exfiltration intent was found.

Report position

Capability review items (2)
Medium
SKILL.md:102
Temp directory access
CACHE="/tmp/my-widget-cache"
The example uses a fixed cache file under /tmp, which can be read or replaced by other local users on shared systems. Use a user-owned cache directory with private permissions.
Medium
SKILL.md:127
Temp directory access
CACHE="/tmp/news-cache" # one headline per line, refreshed by background fetch
The example uses a fixed cache file under /tmp, which can be read or replaced by other local users on shared systems. Use a user-owned cache directory with private permissions.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:57-59
Terminal Pane Content Persistence
The plugin setup enables automatic restore and pane-content capture. This can write terminal output, including tokens or commands, into tmux-resurrect state files.
Line 59 directly enables pane content capture, and lines 57-58 enable automatic restore and periodic saves. This is a clear local privacy risk, although it is not exfiltration.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    Fixed cache files are placed under /tmp.
    Use a user-owned cache directory such as XDG_CACHE_HOME with private permissions and unique filenames.
  2. FIX-002
    Medium
    tmux-resurrect pane content capture is enabled by default.
    Make pane-content capture opt-in and warn users that saved panes can contain secrets.
  3. FIX-003
    Low
    Setup commands modify tmux dotfiles and create a symlink.
    Ask before changes, back up existing tmux files, and show proposed edits before reload.
  4. FIX-004
    Low
    The skill installs third-party tmux plugins and frameworks.
    Ask for confirmation before cloning, prefer pinned versions, and advise users to review upstream repositories.
