OpenClaw versions before 2026.8.1 have a path traversal vulnerability in the tools.fs.workspaceOnly feature. This flaw involves Unicode filename fallback that can normalize parent directory components, allowing an attacker with admitted requester privileges to read files outside the intended workspace boundary. The vulnerability has a medium severity rating with a CVSS score of 5.3.
AI Analysis
Technical Summary
The vulnerability (CVE-2026-100533) in OpenClaw affects versions prior to 2026.8.1. It arises from the tools.fs.workspaceOnly feature's handling of Unicode filename fallback, which can normalize validated parent directory components improperly. This enables an attacker with limited privileges (admitted requester) to exploit canonically equivalent sibling directories to perform path traversal and read files outside the configured workspace boundary.
Potential Impact
An attacker with admitted requester privileges can read files outside the configured workspace boundary by exploiting the path traversal vulnerability. This leads to unauthorized disclosure of potentially sensitive information. There is no indication of integrity or availability impact. The vulnerability requires network access and has a high complexity due to the need for specific conditions involving Unicode filename fallback.
Mitigation Recommendations
A fix is available in OpenClaw version 2026.8.1. Users should upgrade to this version or later to remediate the vulnerability. No other mitigation guidance is provided. Patch status is confirmed by the versioning information indicating the vulnerability affects versions before 2026.8.1.
