{"schema":"threatline.record/2","record":{"id":"CVE-2026-53959","aliases":["GHSA-p77f-p47g-h72p"],"summary":"4gaBoards: Mass Information Disclosure (Internal PII Leakage) on /api/users to any authenticated user","details":"4gaBoards is a boards system for realtime project management. Prior to 3.3.9, 4gaBoards allows any authenticated user to enumerate account information for every user through GET /api/users and retrieve arbitrary accounts through GET /api/users/:id. The users/index and users/show actions rely only on the default is-authenticated policy in server/config/policies.js, and server/api/controllers/users/index.js returns the result of sails.helpers.users.getMany() without requester-specific authorization or response sanitization. Responses expose email, phone, organization, name, isAdmin, ssoGoogleEmail, ssoGithubEmail, and other SSO-linked email fields, including data for administrators. This enables instance-wide user enumeration, privacy loss, and targeted phishing reconnaissance. This issue is fixed in version 3.3.9.","categories":["Unclassified"],"product":"4gaBoards","vendor":"RARgames","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-53959","source_modified_at":"2026-08-21T19:50:12.621Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"4gaBoards","vendor":"RARgames","versions":[{"status":"affected","version":"< 3.3.9"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/RARgames/4gaBoards/security/advisories/GHSA-p77f-p47g-h72p","source_modified_at":"2026-06-11T16:50:44Z","fetched_at":"2026-10-23T22:01:05.715934Z","package":{"ecosystem":"npm","name":"4gaboards"},"range":"<= 3.3.8"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/RARgames/4gaBoards/security/advisories/GHSA-p77f-p47g-h72p","source_modified_at":"2026-06-11T16:50:44Z","fetched_at":"2026-10-23T22:01:05.715934Z","package":{"ecosystem":"npm","name":"4gaboards"},"version":"3.3.9"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.01025,"percentile":0.63287,"score_date":"2026-10-23"},"published_at":"2026-08-18T21:35:55.492Z","modified_at":"2026-08-21T19:50:12.621Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-53959","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-08-21T19:50:12.621Z"},{"source":"GitHub Advisory Database","url":"https://github.com/RARgames/4gaBoards/security/advisories/GHSA-p77f-p47g-h72p","fetched_at":"2026-10-23T22:01:05.715934Z","source_modified_at":"2026-06-11T16:50:44Z"},{"source":"Metasploit","url":"https://github.com/rapid7/metasploit-framework/blob/master/modules/auxiliary/gather/4gaboards_users_info_disclosure_cve_2026_53959.rb","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-06-05"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-53959","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","Metasploit","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/RARgames/4gaBoards/security/advisories/GHSA-p77f-p47g-h72p","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/RARgames/4gaBoards/commit/93099d913cbfdbb1799b4aca19d2d0c2d2a276fb","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/RARgames/4gaBoards/releases/tag/v3.3.9","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-08-21T19:49:46.338715Z"},"exploits":[{"added":"2026-09-29","check":false,"date":"2026-06-05","kind":"Auxiliary module","name":"4gaBoards Mass User Information Disclosure (CVE-2026-53959)","source":"Metasploit","url":"https://github.com/rapid7/metasploit-framework/blob/master/modules/auxiliary/gather/4gaboards_users_info_disclosure_cve_2026_53959.rb"}],"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-08-21T19:50:12.621Z","content_hash":"1ce04a25aa149ba3c0ad209df472c887920a6c05eac11fd3394371d4c47e023d"}}
