    Summary: Duplicate Advisory: Svix vulnerable to improper comparison of different-length signatures

    Details: ## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-747x-5m58-mq97. This link is maintained to preserve external references. ## Original Description The `Webhook::verify` function incorrectly compared signatures of different lengths - the two signatures would only be compared up to the length of the shorter signature. This allowed an attacker to pass in `v1,` as the signature, which would always pass verification.
