AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L

Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.3.12

Description OpenClaw is susceptible to an authentication bypass issue in Feishu webhook mode. This occurs when only the verificationToken is configured, and the encryptKey is not. This allows unauthenticated attackers to inject forged Feishu events and potentially trigger the execution of downstream tools by reaching the webhook endpoint. The issue allows acceptance of forged events.

Recommendations Versions prior to 2026.3.12 should be updated to version 2026.3.12 or later.
