FKIE_CVE-2026-53959

Vulnerability from fkie_nvd - Published: 2026-08-18 22:16 - Updated: 2026-09-09 21:13
Severity
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
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.
