A fix is available — apply it.

OpenClaw before 2026.7.1 contains an authorization bypass vulnerability in the /voice set command that allows non-owner external-channel senders to persist Gateway voice configuration. Attackers with command access can change the voice used by Talk responses for the configured provider, affecting configuration integrity without exposing credentials or granting additional host capabilities.
