hunting-unsafe-archive-extraction skillA

hunting-unsafe-archive-extraction is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt unsafe extraction of untrusted compressed archives: an entry's declared path escaping the destination directory (traversal or an absolute path), a symlink or hardlink entry that a later entry writes through to reach outside, decompression amplification where a small archive expands to exhaust disk or memory, and content or name confusion where an extracted file is later executed, served, or loaded. Covers import, restore, plugin-install, and upload features that unpack archives from users o.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add unboundcompute/security-agent-skills/hunting-unsafe-archive-extraction@git:20260821.4f2a732
Exact content
mdr add unboundcompute/security-agent-skills/hunting-unsafe-archive-extraction@sha256:de55c50c3668a405

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
