Description

OpenClaw (npm package 'openclaw') versions >= 2026.5.28 and < 2026.8.1 mishandle archive listings in the tar.bz2 skill installer: bounded command-output suffixes were treated as complete listings of the archive. A crafted .tar.bz2/.tbz2 skill archive can push prohibited entries out of both retained listings so that entry-count and size checks pass, and the archive is then extracted in full. If an operator approves installation of such a malicious or compromised skill archive, over-limit files or entry counts are persisted in the skill tools directory, consuming disk space or inodes. The issue bypasses OpenClaw's extraction budgets but does not by itself execute archive contents. Fixed in 2026.8.1.
