CVE-2026-100582: OpenClaw Channel Plugins before 2026.8.1 Channel Read Allowlist Bypass

Severity: medium (CVSS 6.5 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.2% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2026-09-26 · updated 2026-10-08
Weakness: CWE-862

Description

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.
