CVE-2026-53845

OpenClaw < 2026.5.6 - Skill-Command Dispatch Hook Bypass via Before-Tool-Call Hook Skipping

Published Jun 16, 2026 CVSS 4.0 · 2.3 Low EPSS < 1% KEV · Not listed

Description

OpenClaw before 2026.5.6 contains a hook bypass vulnerability where skill commands routed through the affected dispatch path skip before-tool-call hook coverage. Attackers can exploit this by sending skill commands through the vulnerable dispatch path to bypass hook-based auditing and policy enforcement mechanisms.

Analysis

Technical impact

OpenClaw before version 2026.5.6 contains a flaw that allows skill commands sent through the affected dispatch path to skip the before-tool-call hook, removing audit and policy enforcement for those commands. This weakness corresponds to CWE-693. The result is that attackers can perform privileged actions without triggering standard logging or restrictions.

Affected Systems

The vulnerability affects the OpenClaw product supplied by OpenClaw, specifically any installations using a version older than 2026.5.6. No additional sub‑release information is provided in the advisory.

Risk and Exploitability

The CVSS score of 2.3 indicates a low severity issue, and the EPSS score of less than 1% shows an extremely low probability of exploitation at the time of this analysis. The vulnerability is not listed in the CISA KEV catalog. The assault vector is inferred to be remote, involving the remote transmission of skill commands via the vulnerable dispatch route, as the description mentions attackers sending skill commands through the affected path but does not detail the exact channel. Overall, the risk to confidentiality, integrity, or availability is minimal, although organizations with stringent auditing requirements may still need to address the bypass.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Apply the latest OpenClaw release (2026.5.6 or newer) to eliminate the hook bypass.
If upgrading immediately is not possible, restrict skill command inputs to trusted sources and disable or segregate the vulnerable dispatch path until a patch is applied.
Review audit logs for unauthorized skill command activity that may have bypassed the hook and investigate any anomalies.
