NVD Description

Note: Versions mentioned in the description apply only to the upstream openclaw package and not the openclaw package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

OpenClaw before 2026.3.8 contains a sender allowlist bypass vulnerability in its Microsoft Teams plugin that allows unauthorized senders to bypass intended authorization checks. When a team/channel route allowlist is configured with an empty groupAllowFrom parameter, the message handler synthesizes wildcard sender authorization, permitting any sender in the matched team/channel to trigger replies in allowlisted Teams routes.
