Title

phpMyFAQ: Missing userHasPermission() in 4 API write endpoints (CVE-2026-24421 Incomplete Fix)

Summary

phpMyFAQ is an open source FAQ web application. Versions prior to 4.1.4 have Missing Authorization in the API CategoryController. CVE-2026-24421 addressed this in the BackupController by adding: $this->userHasPermission(PermissionType::BACKUP). The same fix was not applied to 4 other write endpoints in the public API. All 4 only call $this->hasValidToken() — which checks a shared API key header, rather than the individual user's role permissions. The following APIs are affected: POST /api/v4.0/category (CategoryController::create), POST /api/v4.0/faq (FaqController::create), PUT /api/v4.0/faq (FaqController::update), and POST /api/v4.0/question (QuestionController::create). This issue has been fixed in version 4.1.4.

Vulnerability from github – Published: 2026-06-23 22:27 – Updated: 2026-06-23 22:27

Summary

phpMyFAQ: Missing userHasPermission() in 4 API write endpoints (CVE-2026-24421 Incomplete Fix)

Details

Missing Authorization in API CategoryController — CVE-2026-24421 fixed BackupController by adding userHasPermission(PermissionType::BACKUP). The same fix was NOT applied to 4 other write endpoints in the public API. All 4 only call hasValidToken() (shared API key) but never call userHasPermission(), allowing any API token holder to perform admin operations regardless of their user permissions.

Summary

CVE-2026-24421 fixed BackupController by adding: $this->userHasPermission(PermissionType::BACKUP);

The same fix was NOT applied to 4 other write endpoints in the public API. All 4 only call $this->hasValidToken() — which checks a shared API key header, NOT the individual user's role permissions.

Affected Endpoints

src/phpMyFAQ/Controller/Api/CategoryController.php → create() POST /api/v4.0/category Missing: userHasPermission(PermissionType::CATEGORY_ADD) Any API token holder can create categories regardless of user role.
src/phpMyFAQ/Controller/Api/FaqController.php → create() POST /api/v4.0/faq Missing: userHasPermission(PermissionType::FAQ_ADD) Any API token holder can create FAQ entries regardless of user role.
src/phpMyFAQ/Controller/Api/FaqController.php → update() PUT /api/v4.0/faq Missing: userHasPermission(PermissionType::FAQ_EDIT) Any API token holder can update any FAQ entry regardless of user role.
src/phpMyFAQ/Controller/Api/QuestionController.php → create() POST /api/v4.0/question Missing: permission check Any API token holder can create questions regardless of user role.

Root Cause

All 4 methods only call: $this->hasValidToken(); ← shared API key, not per-user

The fixed BackupController correctly calls: $this->userHasPermission(PermissionType::BACKUP);

PermissionType::CATEGORY_ADD, FAQ_ADD, FAQ_EDIT all exist in src/phpMyFAQ/Enums/PermissionType.php — they just are not being used.

Fix

Add userHasPermission() before the logic in each method:

// CategoryController.create()
$this->userHasPermission(PermissionType::CATEGORY_ADD);

// FaqController.create()
$this->userHasPermission(PermissionType::FAQ_ADD);

// FaqController.update()
$this->userHasPermission(PermissionType::FAQ_EDIT);

The same fix was NOT applied to 4 other write endpoints in the public API.  All 4 only call hasValidToken() (shared API key) but never call userHasPermission(), allowing any API token holder to perform admin operations regardless of their user permissions.\n\n## Summary\n\nCVE-2026-24421 fixed BackupController by adding: $this-\u003euserHasPermission(PermissionType::BACKUP);\n\nThe same fix was NOT applied to 4 other write endpoints in the public API. All 4 only call $this-\u003ehasValidToken() \u2014 which checks a shared API key header, NOT the individual user\u0027s role permissions.\n\n## Affected Endpoints\n\n1. src/phpMyFAQ/Controller/Api/CategoryController.php \u2192 create()  POST /api/v4.0/category\nMissing: userHasPermission(PermissionType::CATEGORY_ADD)\nAny API token holder can create categories regardless of user role.\n\n2. src/phpMyFAQ/Controller/Api/FaqController.php \u2192 create()  POST /api/v4.0/faq\n   Missing: userHasPermission(PermissionType::FAQ_ADD)\n   Any API token holder can create FAQ entries regardless of user role.\n\n3. src/phpMyFAQ/Controller/Api/FaqController.php \u2192 update()  PUT /api/v4.0/faq\n   Missing: userHasPermission(PermissionType::FAQ_EDIT)\n   Any API token holder can update any FAQ entry regardless of user role.\n\n4. src/phpMyFAQ/Controller/Api/QuestionController.php \u2192 create() POST /api/v4.0/question\n   Missing: permission check\n   Any API token holder can create questions regardless of user role.\n\n## Root Cause\n\nAll 4 methods only call:\n    $this-\u003ehasValidToken();   \u2190 shared API key, not per-user\n\nThe fixed BackupController correctly calls:\n    $this-\u003euserHasPermission(PermissionType::BACKUP);  \n\nPermissionType::CATEGORY_ADD, FAQ_ADD, FAQ_EDIT all exist in src/phpMyFAQ/Enums/PermissionType.php \u2014 they just are not being used.\n\n## Fix\n\nAdd userHasPermission() before the logic in each method:\n\n    // CategoryController.create()\n    $this-\u003euserHasPermission(PermissionType::CATEGORY_ADD);\n\n    // FaqController.create()\n    $this-\u003euserHasPermission(PermissionType::FAQ_ADD);\n\n    // FaqController.update()\n    $this-\u003euserHasPermission(PermissionType::FAQ_EDIT);\n\n## Reporter\n\nCONTACT\nSanthoshini Ganta\nGithub:@santhoshinipayload\nEmail: santhoshinive75@gmail.com\nLinkedIn: http://linkedin.com/in/santhoshini-g-1440621ba",
