Summary
generated automatically from NVD dataOpenClaw versions before 2026.4.15 have an authentication bypass in the validation of Feishu webhooks and card actions, letting unauthenticated requests reach command dispatch. When the encryptKey is not configured or callback tokens are blank, the checks fail open rather than rejecting the request. An attacker can thereby skip signature verification and replay protection and execute arbitrary commands. The flaw is rated CRITICAL with a CVSS v3.1 score of 9.8.
