Other vulnerabilities in NamelessMC
See all- CVE-2026-40571Medium
NamelessMC, website software for Minecraft servers, in version 2.2.4 does not enforce blocked/private-profile visibility when adding reactions to profile posts. The file `core/classes/Misc/ProfilePostReactionContext.php` only verifies the post exists. Authenticated low-privileged users can add reactions to private or blocking profile posts. Version 2.2.5 contains a patch.
- CVE-2026-40314Medium
In NamelessMC version 2.2.4, ProfilePostReactionContext.php does not enforce blocked/private-profile visibility, and reactions.php allows unauthenticated GET requests. This allows unauthenticated visitors to read reaction details for private posts and low-privileged users to add reactions to private or blocking posts. Fixed in version 2.2.5.
- CVE-2026-35447Medium
NamelessMC version 2.2.4 processes wall post submissions before verifying profile access permissions. A user with profile.post permission can write to private profiles and inject replies into arbitrary wall posts. Fixed in version 2.2.5.
- CVE-2026-35443Medium
NamelessMC 2.2.4 fails to enforce topic-level view_other_topics authorization when reading and modifying post reactions. A user who can access the forum but only see their own topics can read and modify reactions on other users' topics. The issue is fixed in version 2.2.5.
- CVE-2026-34460Medium
NamelessMC, website software for Minecraft servers, in versions 2.2.4 and prior, does not validate the state parameter server-side during OAuth callback. This allows an attacker to capture a valid OAuth callback URL and swap the victim's session to the attacker-linked account (OAuth login CSRF / session swapping).
- CVE-2026-33398High
NamelessMC version 2.2.4 has a vulnerability in modules/Forum/pages/forum/get_quotes.php that allows low-privileged authenticated users to read content from hidden, private, or staff-only forums by enumerating post IDs. The backend does not enforce forum or topic ACLs.
Original NVD description (English source)
NamelessMC is website software for Minecraft servers. A Reflected Cross-Site Scripting (XSS) vulnerability was discovered in version 2.2.4 in the id parameter of the endpoint `/index.php?route=/queries/user/`. The application reflects user-supplied input from the id parameter into the HTML response without proper sanitization or output encoding. An attacker can craft a malicious URL containing JavaScript code. When a victim visits the crafted URL, the injected script executes in the victim's browser within the context of the vulnerable application. This could allow attackers to execute arbitrary JavaScript, potentially leading to session hijacking, phishing attacks, or manipulation of page content. Version 2.2.5 fixes the issue.
