CVE-2026-100582 · Severity: medium · CVSS 6.5 · Published 2026-09-26

OpenClaw's channel plugins for Microsoft Teams, Feishu, Matrix, and Google Chat are integration libraries that connect chat platforms to the OpenClaw application framework. These plugins fail to enforce access controls when retrieving messages, reactions, pins, and member data from channels, allowing actors with limited permissions to read content from channels they should not access. The practical risk depends on what permissions the connected bot account has on each platform, but unauthorized data exposure is possible.

Technologies: [@openclaw/feishu (npm)](https://junglewise.ai/threats/technologies/openclaw-feishu). Vendors: [npm](https://junglewise.ai/threats/vendors/npm), [Openclaw](https://junglewise.ai/threats/vendors/openclaw).

## Technical details

The vulnerability is a missing authorization check (CWE-862) in channel read operations that process caller-supplied explicit read targets. When a user or steered agent calls message, reaction, pin, or member read actions with an explicit target channel, the plugins fail to validate that the target is in the configured read allowlist before returning data. Network-accessible over authenticated channels (PR:L), with no user interaction required. The fix is available in version 2026.8.1 and later.
