Detailsinfo

A vulnerability was found in OpenClaw feishu, googlechat, msteams and matrix up to 2026.8.0. It has been classified as problematic. Affected is an unknown code of the component Channel Plugin. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality. CVE summarizes:

OpenClaw channel plugins (@openclaw/msteams, @openclaw/feishu, @openclaw/matrix, and @openclaw/googlechat) before 2026.8.1 do not enforce the configured channel read allowlist for caller-supplied explicit read targets in message, reaction, pin, member, and related metadata read actions. A lower-trust sender or a steered agent with access to a channel read action can therefore retrieve content or metadata from channels or rooms excluded by the operator's read policy; the practical impact depends on the permissions held by the connected bot account. The issue is fixed in 2026.8.1.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-100582 since 09/26/2026. The exploitability is told to be easy.
