CVE-2026-100582 (opens in a new tab)How to fix?
Upgrade @openclaw/msteams to version 2026.8.1 or higher.
Overview
@openclaw/msteams is an OpenClaw Microsoft Teams channel plugin
Affected versions of this package are vulnerable to Missing Authorization via caller-supplied explicit read targets in message, reaction, pin, member, and related metadata read actions, which do not enforce the configured channel read allowlist. A lower-trust sender or steered agent with access to a channel read action can retrieve content or metadata from channels excluded by the operator's read policy. The practical impact depends on the permissions held by the connected bot account.
Workaround
Before upgrading, disable explicit-target read actions or limit the connected bot account to allowed channels at the platform level.
