{"id":"CVE-2026-63437","published":"2026-11-06T21:17:09.593","lastModified":"2026-11-09T23:17:24.750","description":"2FAuth is a web app to manage Two-Factor Authentication (2FA) accounts and generate their security codes. Prior to 8.0.0, the recipients() method in app/Api/v1/Controllers/TwoFAccountShareController.php receives a caller-selected TwoFAccount through Laravel model binding but does not call the manageShares authorization policy before listing its recipients. When account sharing is enabled, an authenticated user can call GET /api/v1/twofaccounts/{victimId}/recipients for accounts owned by other users, enumerate registered user IDs and display names, test exact email addresses with filter[nameOrEmail], and inspect each account's sharing relationships. This issue is fixed in version 8.0.0.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-639","CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Bubka/2FAuth/commit/08753afbd847da8fa285e2ad857693ff88e46b84","tags":[]},{"url":"https://github.com/Bubka/2FAuth/releases/tag/v8.0.0","tags":[]},{"url":"https://github.com/Bubka/2FAuth/security/advisories/GHSA-m52c-63g8-qg5c","tags":[]}],"exploitRefs":[{"url":"https://github.com/Bubka/2FAuth/commit/08753afbd847da8fa285e2ad857693ff88e46b84","tags":[]},{"url":"https://github.com/Bubka/2FAuth/releases/tag/v8.0.0","tags":[]},{"url":"https://github.com/Bubka/2FAuth/security/advisories/GHSA-m52c-63g8-qg5c","tags":[]}],"hasPoc":true,"ai":null}
