CVE-2026-40314: CWE-862: Missing Authorization in NamelessMC Nameless
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.
AI Analysis
Technical Summary
NamelessMC, a website software for Minecraft servers, in version 2.2.4 has a missing authorization control (CWE-862) in its profile post reaction handling. Specifically, the file core/classes/Misc/ProfilePostReactionContext.php verifies only the existence of a wall post but does not enforce privacy or blocking restrictions. Additionally, modules/Core/queries/reactions.php allows unauthenticated GET requests to retrieve reaction participants and timestamps for private profile posts. Consequently, unauthenticated visitors can read reaction details on private posts, and authenticated users with low privileges can add reactions to posts they should not access. This vulnerability is addressed in version 2.2.5.
Potential Impact
The vulnerability allows unauthorized information disclosure of reaction participants and timestamps on private profile posts to unauthenticated users. It also permits authenticated users with low privileges to add reactions to private or blocking profile posts, potentially violating user privacy and trust. The CVSS 4.0 score is 6.9 (medium severity), indicating a moderate impact due to network attack vector, no privileges required, and low integrity and availability impact.
Mitigation Recommendations
Upgrade NamelessMC to version 2.2.5 or later, where this authorization issue has been fixed. No other mitigation or workaround is indicated in the available data.
