Summary
SQL Injection via ORDER BY clause in V2Board thru 1.7.4. In app/Http/Controllers/Admin/UserController.php, the sort parameter from user input is passed directly to User::orderBy($sort, $sortType) without validation. An authenticated admin can sort users by any database column including password, remember_token, and other sensitive fields, enabling information disclosure through ordering analysis.

CVE-2026-37504 (GCVE-0-2026-37504)
Vulnerability from cvelistv5 – Published: 2026-05-01 00:00 – Updated: 2026-05-01 19:46
VLAI
Summary
Sensitive server_token exposed via GET parameter in V2Board thru 1.7.4. In app/Http/Controllers/Server/UniProxyController.php, the server authentication token is accepted via GET parameter transmission. The token appears in URLs such as /api/v1/server/UniProxy/user?token=SECRET, causing it to be recorded in web server access logs, browser history, HTTP Referer headers, and proxy/CDN logs. An attacker who gains access to any log source can extract the token and impersonate a proxy server node, potentially intercepting all user traffic.

CVE-2026-39912 (GCVE-0-2026-39912)

Title
v2board / Xboard Authentication Token Exposure via loginWithMailLink
Summary
V2Board 1.6.1 through 1.7.4 and Xboard through 0.1.9 expose authentication tokens in HTTP response bodies of the loginWithMailLink endpoint when the login_with_mail_link_enable feature is active. Unauthenticated attackers can POST to the loginWithMailLink endpoint with a known email address to receive the full authentication URL in the response, then exchange the token at the token2Login endpoint to obtain a valid bearer token with complete account access including admin privileges.
