Missing authorization in NamelessMC 2.2.4 allows authenticated low-privileged users to add reactions to wall posts on private profiles or profiles that have blocked them, bypassing expected privacy and blocking controls. The flaw exists in `core/classes/Misc/ProfilePostReactionContext.php`, which validates only that the target post exists but performs no check against the profile's visibility settings or block relationships. No public exploit identified at time of analysis, and the vendor has released a patch in version 2.2.5.
Authorization bypass in NamelessMC 2.2.4's profile wall system allows low-privileged authenticated users to post to private or blocking profiles, and to inject replies into wall posts belonging to arbitrary profiles they would otherwise be restricted from accessing. The profile.php module processes wall post submissions before performing the visibility and block-list authorization checks, meaning the write completes before any rejection occurs. A second independent flaw in the reply branch skips verification that the target wall post belongs to the profile being accessed, enabling cross-profile reply injection via a restricted profile URL. No public exploit code has been identified and this is not listed in CISA KEV, but a patch is available in version 2.2.5.
Missing authorization controls in NamelessMC 2.2.4 expose private profile post reaction data to unauthenticated visitors and allow low-privileged authenticated users to interact with posts from profiles they are blocked by or that are set to private. Two distinct code paths are vulnerable: the reaction query endpoint in `modules/Core/queries/reactions.php` accepts unauthenticated GET requests without enforcing privacy settings, while `core/classes/Misc/ProfilePostReactionContext.php` only validates post existence rather than caller access rights. No public exploit code exists and this vulnerability has not been added to the CISA KEV catalog, but the unauthenticated read path requires no prerequisites against internet-facing installations.
NamelessMC 2.2.4's forum module exposes a broken object-level authorization flaw that allows authenticated users to read and modify reactions on topics they are explicitly forbidden from viewing. The vulnerability exists in `modules/Forum/classes/ForumPostReactionContext.php`, which enforces only forum-level access (`can view the forum`) but omits the topic-level `view_other_topics` permission check - meaning the access control boundary is incomplete by design. Attackers with a low-privilege forum account in a restricted forum can bypass the `view_other_topics` restriction to interact with other users' topic reactions. No public exploit code exists and this CVE is not listed in the CISA KEV catalog at time of analysis.
OAuth login CSRF in NamelessMC 2.2.4 and prior enables session swapping by exploiting the absence of server-side state parameter validation during OAuth callback handling. An unauthenticated attacker (PR:N) who controls their own OAuth-linked account can capture a valid callback URL and socially engineer a victim (UI:R) into navigating to it, causing the victim's browser session to become authenticated as the attacker's account - effectively hijacking the victim's logged-in state. No public exploit has been identified and this is not listed in the CISA KEV catalog, but the patch to version 2.2.5 is confirmed via GitHub Security Advisory GHSA-pmpw-2xvh-5xj6.
Broken access control in NamelessMC 2.2.4 (Minecraft community website software) allows any low-privileged authenticated user to read posts from hidden, private, or staff-only forums by sending crafted requests to the get_quotes.php endpoint. The Forum module's quote helper only verifies that the caller is logged in and fails to enforce forum/topic visibility ACLs that the normal topic view does enforce. No public exploit identified at time of analysis, but the issue is trivial to weaponize given an account on the affected site.
