CVE-2026-40314 Details
Description
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.
A vulnerability in NamelessMC version 2.2.4 allows unauthenticated users to access reaction details on private profile posts, including participant information and timestamps. This issue arises because the reaction context validation does not consider profile visibility settings. Additionally, authenticated users with low privileges can add reactions to private or blocking profile posts.
Users are advised to update to NamelessMC version 2.2.5, where this vulnerability has been fixed.
