archive-path-traversal

95 / 100 · Low risk

Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

By dreadnode/capabilities (GitHub) · security · 22 stars · scanned at commit 3ceeb34

Craft malicious archives (ZIP/TAR) to test extraction vulnerabilities including Zip Slip, symlink attacks, hardlink collisions, setuid escalation, polyglot bypasses, and Unicode path confusion. Use when a target accepts archive uploads or extracts archives server-side. Triggers on "archive upload", "zip slip", "tar extraction", "symlink", "hardlink", "polyglot", "archive alchemist", "extraction vulnerability".

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'archive-path-traversal' ] || [ -L ~/.agents/skills/'archive-path-traversal' ]; then echo 'A skill folder named archive-path-traversal already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/dreadnode/capabilities' "$d" && git -C "$d" checkout --quiet '3ceeb34c0c33dc36738cf0d4ec86e38b53d98216' -- 'capabilities/web-security/skills/archive-path-traversal' && mkdir -p ~/.agents/skills && cp -R "$d"/'capabilities/web-security/skills/archive-path-traversal' ~/.agents/skills/'archive-path-traversal' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'archive-path-traversal' ~/.claude/skills/'archive-path-traversal' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
