CVE-2026-111891

phpMyFAQ from 4.2.0-alpha.2 before 4.2.0-beta Privilege Escalation via Group Permissions API

phpMyFAQ from 4.2.0-alpha.2 before 4.2.0-beta contains a privilege escalation vulnerability in the group permission API, whose updatePermissions and updateMembers endpoints check held rights without regard to language or category scope and write unrestricted group grants. Non-superadmin administrators holding GROUP_EDIT can grant a group a right they hold only in a narrow scope and self-join it via updateMembers, gaining unrestricted FAQ create, edit, and publish access across all languages and categories.

phpMyFAQ 3.2.0 before 4.0.0 and 4.0.2 before 4.2.0-beta contains an authentication bypass in its Microsoft Entra ID login flow, which links users by the mutable preferred_username claim and whose AuthEntraId::create() ignores the duplicate-login exception while continuing with the existing local account. Attackers controlling an Entra identity in the configured tenant with a matching preferred_username can take over that local account, including super-admin accounts.

phpMyFAQ 3.2.0-alpha before 4.1.9 and 4.2.0-alpha before 4.2.0-beta contains an authentication bypass vulnerability that allows IdP-authenticated users to skip TOTP two-factor authentication through the Keycloak and Entra ID SSO callbacks. Attackers holding a valid or phished IdP identity linked to a 2FA-enabled account can complete the OIDC flow and obtain a fully authenticated session, including administrator accounts.

phpMyFAQ before 4.1.9 and 4.2.0-alpha before 4.2.0-beta does not require the current password when changing an account e-mail in the user control panel (UserController::updateData, api/user/data/update), checking only the session and CSRF token. An attacker with a hijacked session can set the e-mail to their own mailbox and use the password-reset flow to take over non-2FA accounts, including superadmin.

CVE-2026-56738

phpMyFAQ has SQL Injection in `StopWords::add()` — Unescaped Stop Word Insertion

phpMyFAQ is an open source FAQ web application. The `StopWords::add()` method inversions prior to 4.1.6 builds a SQL `INSERT` statement using `sprintf()` and inserts the user-supplied stop word value directly into the query string without calling the application's database escaping function on it. A sibling method, `StopWords::update()`, which modifies an existing stop word, correctly escapes the same kind of input. The omission is isolated to the `add()` (insert) code path. An authenticated administrator who can reach the stop-word management feature can submit a crafted value as the "word" parameter that breaks out of the SQL string literal and injects arbitrary SQL, including statements to drop tables, exfiltrate data, or modify other rows in the database. Version 4.1.6 fixes the issue.

CVE-2026-56737

phpMyFAQ's two-factor authentication login bypasses the password factor

phpMyFAQ is an open source FAQ web application. Versions 3.2.0 through 4.1.5 contain an authentication bypass in its public two-factor authentication verification flow: an unauthenticated attacker can submit an account’s numeric user ID and a valid or brute-forced six-digit TOTP code without first authenticating with the account password, allowing takeover of any 2FA-enabled account, including administrator accounts. Version 4.1.6 is patched by binding TOTP verification to a session established after successful password authentication and limiting failed TOTP attempts. No official workaround is documented; affected installations should upgrade to 4.1.6 or later.

CVE-2026-56736

phpMyFAQ has Stored XSS in Admin FAQ Editor via HTML Entity Bypass in Frontend FAQ Submission

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. The vulnerability exists because `html_entity_decode()` converts HTML entities into executable HTML after `strip_tags()` has already passed them through, and the admin template renders the content with Twig's `|raw` filter without any output sanitization. Version 4.2.0-alpha fixes the issue.

phpMyFAQ: SQL LIKE Wildcard Injection in Chat User Search Allows Authenticated User Enumeration

phpMyFAQ is an open source FAQ web application. Prior to version 4.2.0-alpha, an authenticated SQL LIKE wildcard injection vulnerability in phpMyFAQ’s chat user search allows any logged-in user to bypass the intended display-name search filter and enumerate active users. The endpoint escapes SQL string syntax but does not escape `%` and `_`, which remain active `LIKE` wildcards. Version 4.2.0-alpha patches the issue.

CVE-2026-85590

phpMyFAQ before 4.1.8 Authentication Bypass via Two-Factor Disable

phpMyFAQ before 4.1.8 contains an authentication bypass vulnerability in its two-factor authentication (TOTP) disable functionality. The removeTwofactorConfig() handler (reachable via POST /api/user/remove-twofactor) verifies only that the user is logged in and that a valid CSRF token is supplied, then disables TOTP without requiring password re-entry or a current TOTP code. The same downgrade is also reachable inline via PUT /api/user/data/update, which accepts a plain twofactor_enabled form field under the same session+CSRF-only guard. An attacker who has hijacked a user's session can silently strip two-factor protection from any account, including administrator accounts, after which password-only authentication succeeds.
