Short explanation

phpMyFAQ before version 4.1.9 contains an SQL injection vulnerability in PdoMysql::escape(). Unauthenticated attackers can send a Unicode right single quotation mark in the search parameter of api/autocomplete to read credentials, modify records, or drop tables.

Why does it matter?

Allowing unauthenticated attackers to access sensitive credentials, alter database records, or drop tables poses a severe threat to database confidentiality and integrity.

What should be done?

Follow official vendor security advisories
Upgrade phpMyFAQ to unaffected versions
Review database configurations and operational modes
