{"apiVersion":"1.0","identifier":"CVE-2026-53959","description":"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.","publishedAt":"2026-08-18T22:16:54","lastModifiedAt":"2026-08-21T20:16:37","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53959","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","epssProbability":0.00407,"riskScore":0.67,"affectedProduct":"4gaBoards","affectedVersions":"<3.3.9","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53959","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53959","en":"https://www.redsauce.net/en/cves/CVE-2026-53959","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53959","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53959","de":"https://www.redsauce.net/de/cves/CVE-2026-53959","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53959","el":"https://www.redsauce.net/el/cves/CVE-2026-53959"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53959"}}
