Non-constant time webhook token comparison in Jenkins Generic Webhook Trigger Plugin
Generic Webhook Trigger Plugin 1.84.1 and earlier does not use a constant-time comparison when checking whether the provided and expected webhook token are equal.
This could potentially allow attackers to use statistical methods to obtain a valid webhook token.
Generic Webhook Trigger Plugin 1.84.2 uses a constant-time comparison when validating the webhook token.
