Overview

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to the lack of exposure of the HMAC-SHA256 signing key in the SDK's typed API, which prevents verification of the X-AxonFlow-Signature header on incoming webhook deliveries. An attacker can impersonate legitimate webhook events by crafting forged payloads if they obtain the webhook URL.
