CVE-2026-40314

MEDIUMPre-NVD 6.96.9—Elevated

6.9

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.
