Summary
phpMyFAQ versions 4.0-nightly-2025-10-03 and below do not enforce uniqueness of email addresses during user registration, allowing multiple accounts with the same email. This can cause account ambiguity and, in certain configurations, may lead to privilege escalation or account takeover. The issue is fixed in version 4.0.13.
Risk Assessment
An attacker could exploit duplicate email addresses to take over accounts or escalate privileges, threatening the confidentiality and integrity of application data.
Recommendation
Upgrade phpMyFAQ to version 4.0.13 or later, which enforces email uniqueness during registration.
Other vulnerabilities in phpMyFAQ
See all- CVE-2026-56736High
phpMyFAQ is an open source FAQ web application. A stored cross-site scripting (XSS) vulnerability in versions prior to 4.2.0-alpha allows any unauthenticated user (or low-privileged registered user) to inject arbitrary JavaScript that executes in an administrator's browser when they review or edit a user-submitted FAQ entry. This leads to admin account takeover via session theft.

A vulnerability in phpMyFAQ before version 4.1.5 allows unauthenticated attackers to retrieve inactive (draft or review-only) FAQ content due to inconsistent filtering in public API endpoints.
- CVE-2026-57961Low
phpMyFAQ before version 4.1.5 contains a path traversal vulnerability in the concatenatePaths() function in Wrapper.php.

Original NVD description (English source)
phpMyFAQ is an open source FAQ web application. Versions 4.0-nightly-2025-10-03 and below do not enforce uniqueness of email addresses during user registration. This allows multiple distinct accounts to be created with the same email. Because email is often used as an identifier for password resets, notifications, and administrative actions, this flaw can cause account ambiguity and, in certain configurations, may lead to privilege escalation or account takeover. This issue is fixed in version 4.0.13.
