CVE-2026-28486Public exploit

Arbitrary file writes via unchecked archive paths

Published Mar 5, 2026 · Updated Mar 5, 2026

Path traversal in OpenClaw 2026.1.16-2 through 2026.2.13 allows local users to write arbitrary files through crafted archives. Installation flows pass archive entries containing parent-directory or absolute paths to extraction without rejecting paths that resolve outside the destination. Exploitation requires a user to run a skills, hooks, plugins, or signal installation command on an untrusted local file or download URL, enabling writes with that user's permissions and resulting persistence or code execution.
