Official description

NamelessMC is website software for Minecraft servers. In version 2.2.4, the profile page (modules/Core/pages/profile.php) processes wall post submissions and replies before verifying whether the viewer is authorized to access the profile. This allows any user with the profile.post permission to write wall posts to private or blocking profiles. Additionally, the reply branch does not verify that the target wall post belongs to the current profile, enabling attackers to inject replies into arbitrary wall posts owned by other profiles via a restricted profile URL. This is patched in version 2.2.5.
