OpenClaw channel plugins including @openclaw/msteams before version 2026.8.1 have a missing authorization vulnerability. This flaw allows lower-trust senders or agents with channel read access to bypass the configured read allowlist and access content or metadata from channels or rooms that should be restricted. The vulnerability affects message, reaction, pin, member, and related metadata read actions. The issue is resolved in version 2026.8.1.

Technical Analysis

OpenClaw channel plugins (@openclaw/msteams, @openclaw/feishu, @openclaw/matrix, and @openclaw/googlechat) prior to 2026.8.1 do not enforce the configured channel read allowlist for caller-supplied explicit read targets. This missing authorization allows a lower-trust sender or a steered agent with channel read permissions to retrieve content or metadata from channels or rooms excluded by the operator's read policy. The impact depends on the permissions of the connected bot account. The vulnerability is fixed in version 2026.8.1.

Potential Impact

An attacker or lower-trust user with channel read action access can bypass read restrictions and access unauthorized channel content or metadata. The severity is high with a CVSS 4.0 score of 7.1, indicating significant confidentiality impact without requiring user interaction or elevated privileges beyond low privileges.

Mitigation Recommendations

Upgrade OpenClaw channel plugins to version 2026.8.1 or later, where the missing authorization issue has been fixed. No additional mitigation is required once the update is applied.
