Snowy 3.6.5 contains a hard-coded HMAC key vulnerability that allows unauthenticated attackers to forge download signatures for the /dev/file/download endpoint by using the published FILE_DOWNLOAD_SIGN_SECRET constant. Attackers can compute HMAC-SHA256 signatures of guessed file ids offline to download stored files such as avatars, editor images and attachments.
