Vulnerability Advisory : KiotViet Sync <= 1.8.5 - Missing Authorization to Authenticated (Subscriber+) Settings Update with LOW Attack Complexity

The KiotViet Sync plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the saveConfig() function in all versions up to, and including, 1.8.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update the plugin's config.
