CVE-2026-35447: CWE-201: Insertion of Sensitive Information Into Sent Data in NamelessMC Nameless
NamelessMC is website software for Minecraft servers. In version 2.2.4, the profile page (modules/Core/pages/profile.php) processes wall post submissions and replies before verifying whether the viewer is authorized to access the profile. This allows any user with the profile.post permission to write wall posts to private or blocking profiles. Additionally, the reply branch does not verify that the target wall post belongs to the current profile, enabling attackers to inject replies into arbitrary wall posts owned by other profiles via a restricted profile URL. This is patched in version 2.2.5.

Technical Summary
In NamelessMC version 2.2.4, the profile page (modules/Core/pages/profile.php) handles wall post submissions and replies before confirming if the viewer is authorized to access the profile. This improper authorization check enables users with the profile.post permission to write wall posts on private or blocking profiles. Additionally, the reply functionality does not verify that the target wall post belongs to the current profile, allowing injection of replies into arbitrary wall posts via a restricted profile URL. This vulnerability is classified under CWE-201 (Insertion of Sensitive Information Into Sent Data) and is patched in version 2.2.5.
Potential Impact
Attackers with profile.post permission can post on profiles that should be private or blocking them, potentially exposing or manipulating private communications. They can also inject replies into wall posts belonging to other profiles, which may lead to unauthorized data insertion or manipulation within the platform. The vulnerability does not require user interaction and has a network attack vector with low complexity, but requires privileges (profile.post permission).
Mitigation Recommendations
Upgrade NamelessMC to version 2.2.5 or later, where this vulnerability is patched. Since the vendor has released a fixed version, applying this official update is the recommended remediation. Patch status is confirmed by the vendor advisory indicating the issue is fixed in version 2.2.5.
