AI-suggested
Upgrade Business-GoCardless to version 1.01 or later, where this vulnerability is fixed. The fixed version properly rejects undefined or empty webhook secrets during signature verification, preventing acceptance of forged webhooks.
Description
Business-GoCardless versions before 1.01 for Perl improperly verify cryptographic signatures on webhooks when the configured webhook secret is undefined or empty. This allows an attacker to forge webhooks by signing them with an empty key, which the system accepts as valid. The issue arises because the signature validation function does not reject empty or undefined secrets, which Digest::SHA treats as an empty key.
