CVE-2026-49205: CWE-862: Missing Authorization in thorsten phpMyFAQ
phpMyFAQ versions prior to 4.1.4 have a missing authorization vulnerability in several API endpoints related to category, FAQ, and question creation and update. These endpoints rely only on a shared API key token check rather than verifying individual user permissions, potentially allowing unauthorized write operations. This issue was fixed in version 4.1.4.
AI Analysis
Technical Summary
phpMyFAQ, an open source FAQ web application, has a missing authorization vulnerability (CWE-862) in versions before 4.1.4. While a previous CVE (CVE-2026-24421) addressed authorization in the BackupController by enforcing user permission checks, this fix was not applied to four other write endpoints in the public API: POST /api/v4.0/category, POST /api/v4.0/faq, PUT /api/v4.0/faq, and POST /api/v4.0/question. These endpoints only validate a shared API key token rather than individual user role permissions, which could allow unauthorized users with the API key to perform write operations. The vulnerability is fixed in version 4.1.4.
Potential Impact
An attacker with access to the shared API key could perform unauthorized write operations on categories, FAQs, and questions via the affected API endpoints. This could lead to unauthorized content creation or modification. The CVSS score is 6.5 (medium severity) with high confidentiality impact but no integrity or availability impact.
Mitigation Recommendations
Upgrade phpMyFAQ to version 4.1.4 or later, where the missing authorization checks have been properly implemented on all affected API endpoints. No other mitigation is indicated by the vendor advisory.
