Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

NamelessMC is website software for Minecraft servers. In version 2.2.4, `core/classes/Misc/ProfilePostReactionContext.php` only verifies that the wall post exists and does not enforce blocked/private-profile visibility. This means that authenticated low-privileged users can add reactions to private or blocking profile posts. Version 2.2.5 contains a patch.
