CVE-2026-46359Public exploitNetwork attack vector

Authenticated SQL injection via unescaped OAuth claims

Published May 15, 2026 · Updated May 15, 2026

SQL injection in CurrentUser::setTokenData in phpMyFAQ before 4.1.2 allows remote authenticated users to execute arbitrary SQL. The method formats refresh tokens, access tokens, code verifiers, and JSON-encoded JWT data directly into an SQL UPDATE without database escaping. Exploitation requires Azure AD authentication and an attacker-controlled account claim containing SQL metacharacters; successful injection permits reading, changing, or deleting database content.
