{"id":"CVE-2026-40314","summary":"NamelessMC: Reactions on private or blocking profile posts can be read and modified without proper authorization","details":"NamelessMC is website software for Minecraft servers. In version 2.2.4,`core/classes/Misc/ProfilePostReactionContext.php` only verifies that the wall post exists and does not enforce blocked/private-profile visibility. `modules/Core/queries/reactions.php` allows unauthenticated GET requests for reaction details. This means that unauthenticated visitors can read reaction participants and timestamps for private profile posts and uthenticated low-privileged users can add reactions to private or blocking profile posts. Version 2.2.5 fixes the issue.","aliases":["GHSA-55q9-8qm3-4grc"],"modified":"2026-08-07T11:31:05.938382814Z","published":"2026-06-02T16:08:21.479Z","database_specific":{"cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40314.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40314.json"},{"type":"ADVISORY","url":"https://github.com/NamelessMC/Nameless/security/advisories/GHSA-55q9-8qm3-4grc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40314"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/namelessmc/nameless","events":[{"introduced":"a1ee7ef46718836a3a9a4408cb5bc7c5a08b7efc"},{"last_affected":"a1ee7ef46718836a3a9a4408cb5bc7c5a08b7efc"}],"database_specific":{"extracted_events":[{"introduced":"= 2.2.4"},{"last_affected":"= 2.2.4"}],"source":"AFFECTED_FIELD"}}],"versions":["= 2.2.4","v2.2.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40314.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
