OpenClaw < 2026.2.24 - Path Traversal via @-prefixed Absolute Paths in Workspace Boundary Validation

OpenClaw versions prior to 2026.2.24 contain a path traversal vulnerability where @-prefixed absolute paths bypass workspace-only file-system boundary validation due to canonicalization mismatch. Attackers can exploit this by crafting @-prefixed paths like @/etc/passwd to read files outside the intended workspace boundary when tools.fs.workspaceOnly is enabled.
