AnalysisAIv1 – Sep 15, 2026

Incomplete comparison logic in OpenClaw ClawScan's built-in static scanner (internal/runner/static_scanner.go) through version 0.1.6 lets packaged Python bytecode slip past the deterministic text scan, so malicious skills or OpenClaw plugins can pass inspection undetected. The vendor fix in v0.1.7 (commit 9f6a6fbb9f1137345566d0ab44c73893dfe112fa, PR #41) explicitly adds flagging of packaged Python bytecode as opaque executable content. A publicly available exploit (GitHub issue #40) demonstrates the bypass, but the flaw is local-only, requires a low-privileged local user plus passive user interaction, and yields only a low integrity impact (CVSS 4.0 base 0.9).

DescriptionCVE.org

A flaw has been found in OpenClaw ClawScan up to 0.1.6. This affects an unknown function of the file internal/runner/static_scanner.go of the component Static Scanner. This manipulation causes incomplete comparison with missing factors. It is possible to launch the attack on the local host. The exploit has been published and may be used. Upgrading to version 0.1.7 mitigates this issue. Patch name: 9f6a6fbb9f1137345566d0ab44c73893dfe112fa. The affected component should be upgraded.
