CVE-2026-100533

OpenClaw versions before 2026.8.1 contain a path traversal vulnerability in the tools.fs.workspaceOnly feature where Unicode filename fallback can normalize validated parent directory components.

MEDIUM 6.0EPSS 0.29%

Does this matter?

Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.

Description

OpenClaw versions before 2026.8.1 contain a path traversal vulnerability in the tools.fs.workspaceOnly feature where Unicode filename fallback can normalize validated parent directory components. Admitted requesters can exploit canonically equivalent sibling directories to read files outside the configured workspace boundary.
