Overview
Affected versions of this package are vulnerable to Improper Access Control due to the lack of proper access control checks. An attacker can override the username and icon when making a post, even if the Hardened Mode setting is enabled, by exploiting the settings that allow integrations to override the username and profile picture when posting. This is only exploitable if the settings allow integrations to override the username and profile picture when posting.
