OpenClaw's Microsoft Teams plugin widened group sender authorization when a team/channel route allowlist was configured but groupAllowFrom was empty. Before the fix, a matching route allowlist entry could cause the message handler to synthesize wildcard sender authorization for that route, allowing any sender in the matched team/channel to bypass the intended groupPolicy: "allowlist" sender check.

This does not affect default unauthenticated access, but it does weaken a documented Teams group authorization boundary and can allow unauthorized group senders to trigger replies in allowlisted Teams routes.
