CVE-2026-53854

OpenClaw before 2026.4.25 contains a privilege escalation vulnerability in internal and webchat command authentication that allows senders to inherit wildcard ownerAllowFrom state across channel boundaries. Attackers can exploit this by sending commands on affected internal or webchat paths to execute owner-style command behavior outside intended channel scope, potentially bypassing access controls.

OpenClaw before 2026.4.25 contains a privilege escalation vulnerability in internal and webchat command authentication that allows senders to inherit wildcard ownerAllowFrom state across channel boundaries. Attackers can exploit this by sending commands on affected internal or webchat paths to execute owner-style command behavior outside intended channel scope, potentially bypassing access controls.

Summary

Internal/webchat command auth could inherit ownerAllowFrom wildcard state. In affected versions, a sender on an affected internal or webchat path could inherit wildcard ownerAllowFrom state across channel boundaries.

This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed.

Impact

When the affected feature is enabled and reachable, this could run owner-style command behavior that should have stayed channel-scoped. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path.

Patched Versions

The first stable patched version is 2026.4.25.

Mitigations

keep owner command allowlists explicit per channel until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-4hpg-mp64-x7xq. This link is maintained to preserve external references.
