Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Sync-in Server is a secure, open-source platform for file storage, sharing, collaboration, and syncing.
 Prior to version 2.3.0, the private IP blocklist regex used in the URL download feature does not match
 IPv4-mapped IPv6 addresses (e.g. ::ffff:127.0.0.1), allowing SSRF protection to be bypassed on dual-stack

Update the @sync-in/server library and its related packages to version 2.3.0 or later.
