Overview
@openclaw/feishu is an OpenClaw Feishu/Lark channel plugin (community maintained by @m1heng)
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the installRequestBodyLimitGuard function in the Feishu webhook handler, which applies permissive body size and timeout limits before authentication. An attacker can exhaust server connection resources and block legitimate webhook deliveries by sending multiple slow HTTP POST requests to the affected endpoint.
