CVE-2026-35443 | BDVDB-2026-337301 Detail

NamelessMCNameless

Description#

NamelessMC is website software for Minecraft servers. In version 2.2.4, `modules/Forum/classes/ForumPostReactionContext.php` only verifies that the caller can view the forum, but it does not re-enforce topic-level `view_other_topics` authorization. As a result, in forums where users may enter the forum but may only view their own topics, reactions can still be read and modified on other users' topics. Version 2.2.5 fixes the issue.

Impact#

Per CVSS v4.0: confidentiality impact low, integrity impact low, availability impact none. Attack vector: network.
