Summary

Svix vulnerable to improper comparison of different-length signatures

Details

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.
