CVE-2026-40314

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. `modules/Core/queries/reactions.php` allows unauthenticated GET requests for reaction details. This means that unauthenticated visitors can read reaction participants and timestamps for private profile posts and uthenticated low-privileged users can add reactions to private or blocking profile posts. Version 2.2.5 fixes the issue.
