{"id":"CVE-2026-33398","state":"PUBLISHED","title":"Authenticated users can read hidden forum posts through `/forum/get_quotes`","description":"NamelessMC is website software for Minecraft servers. In version 2.2.4, `modules/Forum/pages/forum/get_quotes.php` only checks whether the caller is logged in, then reads a post by attacker-controlled `post` ID and returns its content. The backend helper in `modules/Forum/classes/Forum.php` does not enforce forum or topic ACLs. In contrast, the normal topic page in `modules/Forum/pages/forum/view_topic.php` enforces forum visibility and `view_other_topics`. Any low-privileged authenticated user can enumerate post IDs and read content from hidden, private, or staff-only forums. Version 2.2.5 fixes the issue.","publishedAt":"2026-06-02T15:19:29.824Z","updatedAt":"2026-06-02T17:08:08.919Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["NamelessMC Nameless"],"affected":[{"vendor":"NamelessMC","product":"Nameless","versions":[{"version":"= 2.2.4","status":"affected"}]}],"references":["https://github.com/NamelessMC/Nameless/security/advisories/GHSA-2r6x-cv4f-h8fx"],"weaknesses":["CWE-285"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/33xxx/CVE-2026-33398.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-33398","state":"PUBLISHED","datePublished":"2026-06-02T15:19:29.824Z","dateUpdated":"2026-06-02T17:08:08.919Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-19T17:02:34.169Z"},"containers":{"cna":{"title":"Authenticated users can read hidden forum posts through `/forum/get_quotes`","descriptions":[{"lang":"en","value":"NamelessMC is website software for Minecraft servers.
