CVE-2026-32016: OpenClaw < 2026.2.22 - Path Traversal via Basename-Only Allowlist Matching on macOS
OpenClaw versions prior to 2026.2.22 on macOS contain a path validation bypass vulnerability in the exec-approval allowlist mode that allows local attackers to execute unauthorized binaries by exploiting basename-only allowlist entries. Attackers can execute same-name local binaries ./echo without approval when security=allowlist and ask=on-miss are configured, bypassing intended path-based policy restrictions.
Security readout for executives and security teams
Plain-English summary
CVE-2026-32016 affects OpenClaw on macOS before version 2026.2.22. A local user can bypass intended execution approvals when OpenClaw is configured to use allowlist mode with ask-on-miss. The issue can let an unauthorized same-name local binary run without approval, undermining endpoint execution controls.
Executive priority
Prioritize remediation for managed macOS endpoints where OpenClaw enforces execution approvals. The issue can weaken a security control meant to prevent unauthorized binaries, but current sources do not indicate internet exposure or active exploitation.
Technical view
OpenClaw’s exec-approval allowlist mode performed basename-only matching. On macOS, versions before 2026.2.22 may approve a local binary with the same filename as an allowlisted entry, bypassing intended path-based restrictions. The CVSS 3.1 score is 7.8 with local attack vector, low complexity, low privileges, and high CIA impact.
Likely exposure
Exposure appears limited to macOS systems running OpenClaw before 2026.2.22 with security=allowlist and ask=on-miss configured, especially where allowlist entries rely on basename-only matching.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires local access and a vulnerable OpenClaw configuration, but no user interaction is required per CVSS.
Researcher notes
Key scoping variables are OS, OpenClaw version, and exec-approval configuration. The advisory describes a policy-bypass condition, not a remote compromise. Public evidence in the bundle identifies a patch commit but does not provide KEV confirmation or active exploitation claims.
Mitigation direction
Upgrade OpenClaw on macOS to version 2026.2.22 or later.
Review vendor advisory and patch commit for official remediation details.
Identify and reassess basename-only allowlist entries in affected configurations.
If upgrade is delayed, avoid relying on the affected allowlist mode until vendor guidance is applied.
Validation and detection
Inventory macOS hosts running OpenClaw.
Confirm installed OpenClaw versions are 2026.2.22 or later.
Check whether security=allowlist and ask=on-miss are enabled.
Review allowlist policy entries for basename-only matches.
Monitor OpenClaw release notes and advisories for updated guidance.
