CVE-2026-35672: Initialization of a Resource with an Insecure Default in thorsten phpMyFAQ
phpMyFAQ before 4.1.3 contains an authentication bypass vulnerability in API v4.0 where the default empty api.apiClientToken allows unauthenticated users to create and modify FAQ entries. Attackers can send an empty x-pmf-token header to bypass token validation and inject malicious content via POST endpoints /api/v4.0/faq/create, /api/v4.0/category, and /api/v4.0/question.
AI Analysis
Technical Summary
CVE-2026-35672 describes an authentication bypass vulnerability in phpMyFAQ before version 4.1.3. The issue arises because the default api.apiClientToken is empty, allowing unauthenticated users to bypass token validation by sending an empty x-pmf-token header. This flaw affects API v4.0 POST endpoints /api/v4.0/faq/create, /api/v4.0/category, and /api/v4.0/question, enabling unauthorized creation and modification of FAQ content.
Potential Impact
The vulnerability allows unauthenticated attackers to inject and modify FAQ entries without valid authentication tokens, potentially leading to content manipulation and integrity loss. The CVSS score of 7.5 (high severity) reflects the ease of exploitation (network accessible, no privileges or user interaction required) and the impact on integrity. There is no indication of confidentiality or availability impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the vulnerable API endpoints or disable API v4.0 if possible to prevent exploitation.
