OpenClaw versions prior to 2026.2.26 contain a path traversal vulnerability in workspace boundary validation that allows attackers to write files outside the workspace through in-workspace symlinks pointing to non-existent out-of-root targets. The vulnerability exists because the boundary check improperly resolves aliases, permitting the first write operation to escape the workspace boundary and create files in arbitrary locations.
