GHSA-wv26-j37q-2g7p: OpenClaw's Slack plugin approvals used the exec approver gate for plugin actions

Slack plugin approvals used the exec approver gate for plugin actions. In affected versions, a Slack user authorized only for exec approvals could resolve a plugin approval through the exec approver gate.

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.
