OpenClaw: Channel read actions could skip target allowlists

### Summary Channel read actions could skip target allowlists. In affected versions, explicit read targets in Microsoft Teams, Feishu, Matrix, and Google Chat could reach channels or rooms outside the configured read policy. This advisory is scoped to caller-supplied targets for message, reaction, pin, member, and related metadata reads in the named plugins. It does not change OpenClaw's trusted-operator model or create per-user isolation within one Gateway. ### Impact A lower-trust sender or steered agent with access to a channel read action could retrieve content or metadata from a target excluded by the operator's channel allowlist. Practical impact depends on the bot account's platform permissions. ### Patched Versions The first stable patched version is `2026.8.1`. ### Mitigations upgrade each affected channel plugin to `2026.8.1` or later. Before upgrading, disable explicit-target read actions or limit the connected bot account to allowed channels at the platform level.
