OpenClaw < 2026.2.1 Authentication Bypass (GHSA-mp5h-m6qj-6292)

high Nessus Plugin ID 299793

Language:

Synopsis

The remote host is affected by an authentication bypass vulnerability.

Description

The version of the OpenClaw AI assistant installed on the remote host is prior to 2026.2.1. It is, therefore, affected by an authentication bypass vulnerability:

 - If channels.telegram.webhookSecret is not set when in Telegram webhook mode, OpenClaw may accept webhook HTTP requests without verifying Telegram's secret token header, allowing forged Telegram updates that could lead to unintended bot actions. (CVE-2026-25474)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to OpenClaw version 2026.2.1 or later.
