{"id":"CVE-2026-53959","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.","aliases":["GHSA-p77f-p47g-h72p"],"modified":"2026-09-11T03:31:01.914185650Z","published":"2026-08-18T21:35:55.492Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53959.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-200"]},"references":[{"type":"WEB","url":"https://github.com/RARgames/4gaBoards/releases/tag/v3.3.9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53959.json"},{"type":"ADVISORY","url":"https://github.com/RARgames/4gaBoards/security/advisories/GHSA-p77f-p47g-h72p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53959"},{"type":"FIX","url":"https://github.com/RARgames/4gaBoards/commit/93099d913cbfdbb1799b4aca19d2d0c2d2a276fb"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rargames/4gaboards","events":[{"introduced":"0"},{"fixed":"93099d913cbfdbb1799b4aca19d2d0c2d2a276fb"},{"fixed":"96cec781dc3e8857a22cb7b2b0adddf27b59748d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.3.9"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v3.3.8","v3.3.7","v3.3.6","v3.3.5","v3.3.4","v3.3.3","v3.3.2","v3.3.1","v3.3.0","v3.2.16","v3.2.15","v3.2.14","v3.2.13","v3.2.12","v3.2.11","v3.2.10","v3.2.9","v3.2.8","v3.2.7","v3.2.6","v3.2.5","v3.2.4","v3.2.3","v3.2.2","v3.2.1","v3.2.0","v3.1.10","v3.1.9","v3.1.8","v3.1.7","v3.1.6","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.8","v3.0.7","v3.0.6","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v2.0.24","v2.0.23","v2.0.22","v2.0.21","v2.0.20","v2.0.19","v2.0.18","v2.0.17","v2.0.16","v2.0.15","v2.0.14","v2.0.13","v2.0.12","v2.0.11","v2.0.10","v2.0.9","v2.0.8","v2.0.7","v2.0.6","v2.0.5","v2.0.4","v2.0.3","v2.0.1","v2.0.0","v1.10.7","v1.10.6","v1.10.4","v1.10.3","v1.10.2","v1.10.1","v1.10.0","v1.9.2","v1.9.1","v1.9.0","v1.8.9","v1.8.8","v1.8.7","v1.8.6","v1.8.5","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.7","v1.7.6","v1.7.5","v1.7.4","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.0","v1.5.2","v1.5.1","v1.5.0","v1.4.1","v1.4.0","v1.3.2","v1.3.1","v1.3.0","v1.2.1","v1.2.0","v1.1.6","v1.1.5","v1.1.4","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.0","v1.0.0-beta.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53959.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
